II: People in their 20s or older who use "going on" when talking about their age. It's usually early 20s, and it tells me a lot about the maturity level. You're not "20 going on 21" - everyone knows 21 comes after 20. You're just 20. It doesn't make you sound older when you say "going on 21" - it makes you sound like you're six.
II: People who insist on using "pre-engaged," "unofficially engaged," or "engaged to be engaged." STOP. Those aren't things. You're either engaged or you're not engaged.
UO: People who get pissed when others post about a TV show days after. Immediate spoilers, yes, those are dickish (and I admit to doing that without thinking a couple times), but a few days or a week later? Calm down.
Confession: I find myself staring at my ring far more often than I probably should. I also have totally been slacking off at work and spending most of my day looking up wedding stuff. Sorry I'm not sorry.
