dear internet,
when i was 4 y/o, i took part in this folklore party where we perform a fake wedding, with dance and typical food, etc. i was the bride. the groom, who went to classes with me, wasn't really a friend, it was all decided by our teachers, and he moved out of the city the next year.
then last year i found him on orkut, and we've chatted on msn sometimes since then, and yesterday the chat was a bit different. we were talking about a party we were both invited to go (by different people), but i wasn't going because i was tired and he said he wasn't going because his loins were hurting. from wrong exercises in the gym, but when he got to explain this, we were already talking in puns, and then i told him i was going to invite him out next week for the movies, because it was harmless enough for his loins. then much laugh followed and we exchanged phone numbers and i left the chat.
today i realized i'll be really busy next week and i'll have some time just on saturday, so i'm thinking i should tell him that asap because people always plan early for saturdays. but i'm still not sure he understood i meant it seriously, about calling him out, and i'm totally insecure about myself too, because he's really gorgeous and he knows that (he put pics on internet of him wearing only a speedo).
so, should i sent him an sms telling him i was serious and when i'll be free?
