Maybe its not quite rejection, its just that people don't really care.
Some people (usually girls....hey I'm just saying!) post something really inane and possibly with a picture of themselves, and they get at least 5+ comments.
If you have almost no social pull, nobody really is going to care about whats going on in your life or your status update. Makes sense, and thats the way mine is.
I have to really control myself from getting jealous when some guy has all of these girls commenting on his statuses and in pictures with him. And then I feel like man how did I f**k up so bad life, where I have none of that, and they have it all. If that guy didn't have a girlfriend, there would be 5 other girls ready for him. damn
