in trouble

hey guys...today there was kinda a big event as Ryan and some of the guys have planned a birthday party for Rashdan...it is next wk @ J8...each of us have to pay an amount of money for the birthday cake...Ryan say he would pay for everything else we were doing...but i'm not sure as it will cause a lot of money...well i didn't know much about what we were going to do...when i told my mum,she scolded me for not asking without their permission and gave the money to them...well i agree that i was quite gullible to give them money without knowing whats going on...but i do trust Ryan...After all why would he bluff some of us into thinking that he is going to treat us but in the end he is not paying?After all we have been classmates for about 1/2 a year...hmmm...still qutie worried...because the plans after all are a bit unclear to me
