Dear *scrie un nume*,
Hi! How are you? I'm writing this email to remind you that on the 16th of March is my birthday and you are invited to the party.
This year I decided to celebrate my anniversary at the local theatre, the one on King's Avenue. The movie is a surprise, so I won't tell you. What I can tell you is the time it starts: 14:45. After the movie I was thinking we can go to a restaurant. It is to be decided.
Hope I will see you there.
Yours, * scrie-ti numele
