About a year ago, the little thingy in the toilet broke (see my technical jargon

?) I went to the hardware store and the man told me to replace it would only take 15 minutes. He explained what I needed to do, so I bought the piece and went home secure in the knowledge that I COULD DO IT.
I arrived home and started to work on fixing the 15 minute toilet job...well 8 hours later

after having flooded the entire upstairs bathroom (he left out the part about turning off the water...I guess I was supposed to KNOW that

)...I finally had it fixed enough for me to go ahead and call the plumber.
