Hey!
I'm really sad that you couldn't come to my birthday party. Everyone had so much fun, and you weren't there. Anyway, I wanted to let you know what I enjoyed the present you sent me. Actually, I enjoyed all of my presents! I got a new phone, a pair of shoes, many sweets and a new bed sheet, because I needed it very much lately. I had great fun at the party but I really wanted you to be there. Maybe we can meet on the weekend to talk about everything?
Bye!
XYZ
