I've been friends with Sarah for 16 years and live on opposite sides of the UK.
Over the years I've visited her a lot and since I bought my own home 4 years ago she has come to visit once a year.
This year she came at an inconvenient time while I was on a trip with a partner so I left the keys with another friend who let her in. I gave her a key so she could come and go.
She has now bought concert tickets for the weekend of my birthday in my city, so second visit this year. She asked if I will be home for my birthday or not and that she was thinking of 'coming on the Friday' which is my actual birthday!
Last year we did spend my birthday together and she chose to spend her birthday with me. Since then I have a partner although I know he'd be flexible about when to see me. And I often spend time with family.
I was planning to go to the theatre in London my birthday weekend but now I am wondering to go another weekend to see her instead.
