Maybe they will annoy me less if I write them down.
When planning a party:
People who don't bother to RSVP. I assume these people aren't coming, but it would be nice to know. Like, even an email would be fine.
People who say they'll be there and then don't show up. Common courtesy I think would at least be a phone call afterwards saying "so sorry, we were deathly ill and couldn't make it." Or whatever the excuse of the day may be.
People who don't RSVP and then show up anyway, sending me scrambling to find more chairs.
Okay I kind of hate party planning, and twice in two weekends is threatening to make my brain explode.
Other things that annoy me:
People who write "U" and "R" instead of "you" and "are." And other things like that too. I'm down with the LOL and the BTW, but when someone writes and says "I want 2 get chickens from U, R U selling any" I don't want to reply, and dudes, you need to know that when you send me a note that says "How R U?" you lose major IQ points in my book and that's pretty much an instant dealbreaker. Call me picky, I just HATE THAT. Really, is it THAT DIFFICULT to write a few more letters and not look like a flaming idiot? And I only thought about being an English minor in college, thank goodness it didn't go any farther.
