i have a theory that they are all very insecure and have no confidence in themselves or their relationship with others and therefore feel the need to advertise that they have sustained contact with another human being for a suspended amount of time. that's why you see all these people who try very hard to fit into the "popular" niche and get with other people on that same wavelength and they cling to each other and feed off of each other's popularity, gaining mutual friendships and such, all the while yelling about it on facebook, screaming into an ether where nobody is really listening, trying to prove to everyone on their friends list that someone actually appreciates their existence, and they're addicted to it, so when it doesn't work, they just search for the next most "popular" person to attach themselves to, so that nobody thinks they are lonely, and so that someday in the future, we will all be quite jealous of their 4th wife/husband's physical attributes (when in reality we just secretly fantasize about hate-fucking them), or whatever.
