It does depend on what you count 'social life' to be. some people (and no offense here btw) seem to think it is time spent with either people you dont know personally, or those you do know but are online. This is PERFECT for some. For others it is getting pissed at a nightclub, and then the possibility of either 'getting laid' (Male) or getting raped (female). again, no offense, this is what i have picked up on from OTHER PEOPLE. For me, its inbetween. I like mixing with people whom i dont know [literally], therefore i can act how i want according to the suituation. But then again, i do like the odd 'piss up'. These are best saved for your local, and actual, 'true' friends. This is when no one judges you for the way you act, because they already know what you are like, and accept you for what you are like, sometimes even praising what you are doing.... heh, sawing that shed in half was a ball!!!

Ahem, in short, and so not to sound like the pompus ass (as i did in the first paragraph) its about having an even mix, or personal prefference (eg, you prefer staying slightly anoyonmus, go for it).
