I am very lazy, sometimes I wait for a long time to reply the messages, I think this is the reason why some of friends stop contacting with me (so sad haha), anyway I just want to say I prefer longer message than just leave one and said "hi how are you?". If you really want to get to know me, I am sure that it won't be a problem for you. But I don't guarantee that I will reply you. If you wait for more than 1 month without getting my message back, it means... I'm sorry dude, thanks for your effort, but I am just not INTERESTED! Don't think I am arrogant, this is the most efficient way to know "real friend" in "cyber world".
