I think you need to look at how sincere and or fake these people are bieng in their descriptions, photos of people in nightclubs flaunting around and posing to the camera, there is nothing wrong with it but you get people bragging about how often they go drinking, what does it mean? it means jack shit in the long run ...i could care less about that ...thats all apart of the scenery ...
if i have something in common with another person and we enjoy each others time together, the rest is peripheral, so its never a competition of popularity for me ..
so try and respect yourself for who you are and dont judge yourself on the basis of how much you drink or whether you go to clubs all the time or if your interesting enough..
wehn i was 18, 19 i frequented bars and its nothing special ..
find what makes you tick, not what you want others to think of you and just roll with it, focus on your individual interests and then you can discuss them with people on those networking sites. . ..
