I can't stand the showing videos thing. I see people doing that shit in public all the time, at the mall, the gym, a parking lot, a group standing around watching a video on that weenie iphone screen with that terrible tinny audio. That's another thing I can't stand, people playing music on their iphone speaker at full volume and it sounds like garbage.
Anytime I get the "Hey watch this" I'm like "No, I don't care and I'm not watching it." I get weird looks but seriously, I DON'T CARE.
