founded !

I found i was different to other.. why ? why when they sad, they need to go out and having some fun.. why I'm not ? When I'm sad, I just prefer to stay at home and for the whole day.. and why I just want to keep silent mode to my phone and does not want to be disturb by anyone else. Why when people sad, they having their food in big portion ? Why I'm not ? I'm not have any appetite to do that ? Why , Why and Why ?
