He was partially disabled with cerebal palsy, which we knew going in, but this mess had zero to do with a physical ailment.
He showed up high (on crack, if I read the signs right) and and even recognizing that fact I let him start. I won't pretend I did that for anything other sympathy for his CP.
He managed all of this damage in 10 minutes and when I saw it there went the last of my sympathy went bye-bye and I kicked him out of the house. He had the nerve to complain loudly that I hadn't paid him for the job.
Now comes the hard part: fixing all this.
