cheat~

Chatted with a guy, or should i say a liar lsat 2 days, only once, then the last time i chatted with him.... This guy chatted with me by using 2 ID, one was a girl and one was a boy, actually he was the one for the 2 ID of the messenger. He told me that he got my MSN in friendster, asked whether can be friend? I treated him quite cold for first, cos he was asking questions that i don't wanna answer. Then, he chatted with me with another account, since HE told me that HE is a girl, so i treated HER nicely, whatever SHE asked, i answered HER. But i found that the questions SHE asked was a bit seems like the the guy just now. I started doubt. After few times i asked him, finally he admited that he was using 2 accounts to chatted with me, i was so angry, cos i hate people cheat. Finally, i have delected the both accounts from my friends's list, and blocked the both account as well.. Sigh, it is fun to cheat like this? Or he was too free and nothing to do at home? Really can't understand~
