Leaving 3 potato chip crumbs in the bag, then putting it away instead of eating the 3 crumbs and throwing out the bag.

Ditto for the ice cream container. Just be the one to finish it already.
Anyone but me doing my laundry or cleaning my bathrooms. My mother-in-law still hasn't learned that this really makes me nuts. Stay outta my dirt!
Too many home parties- I was invited to way too many a while back and it makes me uncomfortable to go and not buy anything. So now I have a toe ring (that I will never be able to cram back on my toe), a pizza stone, some vitamins and weight loss tea (yeah right), some awful lipstick, moisturizer my dermatologist said was deadly, and some stupid looking flowerpots.
Wish someone would invite me to one of those sexy stuff parties. I could get a P-cake mold.
