Prior to this year, I had probably written 15 checks in my lifetime... and that seems like a high guess.
This year though, rent is check - and one of my roomies has all the utilities billed, so I cut a check for utilities every month too.
I hate checks - it's much, much easier to "balance" my accounts when I have no checks, because if it's not a check, it basically shows up on my account instantly. Well, online bill pays actually takes two or three business days to actually post/deduct from my account - but I've gotten into that rhythm just fine. It's the, oh, two weeks later and I know I appear to have far more money that I would expect... oh, I see, that damn check still hasn't posted. ugh.
That's created an ugly situation once or twice.
