Where's it?

I wanna share about my bestfriend, its a He. I dont know if we still regard each other as bestf like the previous time. We used to be close, very very close last year. From stranger to friend to close friend and to bestfriend. Hmmm.... We treat each other like what happy bestfriend normally did. And yeah, I remembered we had a huge arguement which we didnt talk for weeks. Lol, thats normal in friendship. I do still remembered everything about us. See, memory power and sweet eh. Lol. If you dont believe me, ask me then. Lets skip to that. So when it comes to this year, we're starting to fade away/seldom contact. I know we're both busy with our own life. Im not blaming you for the "seldom contact thang". You used to be fun to talk/hang around with, and I meant my words. But this year... Youre somewhat a boring person. Where's the old you man? The one who never failed to support/advice me in everything, the one who always reminded me not to look at the negative part of life when I'm down. The one which I know a positive person. Yeah I know people change blahblah. Really sorry, I didnt mean to hurt your feelings but yeah I have to admit it somehow, super boring. You know I'm always here when you need me. I dont know whats up with you when it comes to communicate with each other (not including the meet up), its like we just get to know each other, dont have a topic to talk about when it comes to Msn, which infact, we have already known for 3 to 4 years. Youre just weird. Dont tell me this is the new you? I know I cant be demanding to want the old you back. Its just that, I miss the old you, seriously. I dont know eh when it comes to meet up. Prove me wrong. So tell me, who's the one to blame?
