My birthday is on 15th of April. My last b-day party was really great! I had a lot of fun with my friends especially when we were playing hide-and-seek. I organized the party. Fist of all, I made a list with those who I want to see there, there were only the most close friends of mine. I made the invitations by myself and sent them by post. At the party we were talking a lot, making funny photos and of course we were playing mafia! We like it very much! It was a great surprise when my friends started singing a special song for me, just as in our childhood. I said them that I don't want any presents, as usual. It was really great! I like all b-day parties but that one was the best!
