help please freaking out slightly

A question about : help please freaking out slightly

At Xmas my dad who lives overseas sent a letter and inside was a card for his twin sister which he asked me to post for him.
I have never met said twin, at least not that I remember, my dad left when I was 2 so assume contact with his family broke down then.
The address on the card was literally just round the corner so I popped in a little note saying how lovely it would be to meet.
Well last night she phoned!
I didn't pick up as I don't answer unkown numbers but she left a lovely message saying she would like to meet up.
She suggested a day out, or a night out, meeting for a drink.
The day put suggestion seemed slightly weird but she did falter over it so perhaps that popped out before she thought about it.
I need to phone her today which I am very nervous about, but I also need to suggest where to meet.
Do I invite her here, perhaps meet for coffee, lunch, a drink in the evening.
Not sure which would be more relaxing and less intense, I have hearing problems and although I wear a hearing aid still struggle in loud places.
Oh in such a tizz.
Any advice on the first phone call appreciated too.

Best answers:

• I would suggest initially arranging to meet for a coffee away from home. If you really click and conversation is flowing then you can extend the time you have together and maybe have lunch too. It is understandable that you feel nervous. You always come across well on here so just be yourself and I hope you will really enjoy chatting to and getting to know your aunt.
• I'd agree with the public place, but what about background noise? You don't want to put any extra stress on yourself. Can you think of anywhere that doesn't have music as default, with quiet corners? My mother was deaf so I do understand about hearing aids amplifying everything as well as the other person's voice Wow, what a surprise!
  Just phone her, say hello, say it would be nice to meet a long lost relative, how you are so surprised by all this you don't really know what to say. and suggest somewhere to meet. Tbh, just incase you don't want to stay in contact due to any strangeness she might have, I really would think somewhere not your home would be best. I hope she turns out to be a lovely new person to have as part of your family.
• Meet at a cafe at a quieter time if day. Obviously lunch times are very busy so louder. Maybe 10 ish???
• How lovely for you to be able to meet your aunt - I do hope all goes well.
  I can't offer any better advice than that already given, except to say that she will probably be just as nervous as you are at the moment. Be yourself and you'll be OK.
  Very best wishes. x
• I'd either meet in a quiet coffee shop in the morning or in a hotel bar in the evening if you need some liquid courage. Hotels tend to be fairly quiet.
• Thank you all for your kind words, just got off the phone with her. Bit awkward at first as she thought her phone was set too loud but it was actually because I tend to shout on the phone due to my deafness! However, she was lovely, we've arranged to meet at morrisons cafe at ten am, I have to leave to pick daughter up at latest half past eleven so nice amount of time I think. If need to escape can always have to pick up bits from the shop.
  She asked if I have a husband or partner and was thrilled when I told her I had 3 children.
  Her and her husband couldn't have children but not sure about other neices and nephews.
  Soo very lovely, came off feeling happy and excited.
  I'm going to take a few photos to show her of the children etc think that mat break the ice.
  Lovely, made my Sunday.
• Ah I am so glad for you that the initial contact with your aunt went so well. I hope you will both have a lovely time.
• Lovely news! It sounds like you have made a good plan for the initial meeting. I too hope it all goes well and is the start of something very good for both of you.
• Exercise a bit of caution. You don't know anyone well enough after one coffee to decide whether you want to be friends with them, and if she's literally in the next street from you it might be difficult to extract yourself if you suggest, or imply, that you want her involved in your own and your children's lives and then in a few weeks or months time she doesn't turn out to be quite that wonderful after all.
• Yes I would meet in a public place, a coffee shop or somewhere similar.
  I'd take along some photos of you as a child (if you have any) so that if the conversation gets a bit flaky you can show her those and you can discuss family resemblances etc.
