a. I think that what I'm doing is cooler than what you're doing, and you should definitely give a crap. Or in the same category, I'm having a great time without you...in your face!
b. I'm just a little bit miserable and I'm hoping to hear from someone who is just a little bit miserable too...after all, misery loves company.
c. I really am looking for someone to sell my microwave to!
d. I'm looking for some connectedness in a digitalized world.
Maybe we do just genuinely want to know what's going on with our friends and they want to know what is going on with us, but sometimes it can seem like a narcissistic exercise when people post things that only someone who is ridiculously infatuated with them would care about. In the words of Dr. Kelso (sorry, I'm on a 'Scrubs' kick): "Who has two thumbs and doesn't give a crap? ME!"
