This is Strange???

Hmmn, something really strange happened recently. I’ve got this guy friend who was pretty nice to me. After CNY, he suddenly became very cold towards me. No replies for sms sent and even though there was, it was just a short & lame one. I wonder what had happened that made him changed his attitude towards me. Did someone speak ill of me to him or he is this kind of person who got attitude problem? I thought he was busy and didn’t have time to reply me, but seems like this is not the case. I am pretty sure something must have happened but I just don’t know what it is. However, if I do find out that someone is behind all these, he/she better have a very good reason to explain to me.
