Don't you just freaking hate it when...
You find a screw laying on the floor and don't know what it goes to...might have fallen out of something important.
You get done painting a room, clean up your mess, put the paint away and THEN discover you missed a spot.
You buy something at the store, get it home and it doesn't work.
Have a headache and discover you are out of Advil/etc.
Have company over for dinner and screw up the meal....or get down to some gourmet cooking only to get started and discover you are missing one itty-bitty but important ingredient.
Take a shower and THEN remember ALL the towels are in the dryer.
You're running late...and it's no one's fault but your own.
Discover your drinking the last beer.
Anyone ? Anyone ? Beuler ?
