SHOULD'VE, COULD'VE, WOULDN'T'VE

I SHOULD'VE put the lid on the paint can tight, put it away and cleaned up a little after I painted our long wall;
I COULD'VE gone to the bathroom at the restaurant so that later I may not have been doing the pee dance in the dark as I made my way through the house;
Then maybe I WOULDN'T'VE kicked over a gallon of green paint causing it to ooze all over the tile floor and into the grout!

* Thankfully it wiped off the tile nicely, I was worried about having green grout, but with a wet towel and some elbow grease, you can't even tell! If this had been on the carpet it would have been disastrous! We'd have to replace all the carpet... Hmmmmm not a bad excuse!
