the whole "here's what i'm having or had for dinner" thing is as mysterious as stonehenge to me. it's like they're rubbing it in your face, but it's also weird that people want to share that info in the first place.
i have one friend who updates everyone on all the errands she runs and when she pays bills.
i have another friend who only posts weather updates. "well, big surprise, it's snowing again here in montana . . ." or "not a bad day. got all way up to 14 this afternoon."
i'm also kind of tired of seeing people who lean WAY in to take a photo. just stand up straight, doofus.
