Not work on your house

First off I'm more of a destructive person than a constructive person. That being said The bank is a little tight and we had a faucet to put in. Easy I've done it before. 3 other times to be exact. First I break the hose connecting the cold water to the faucet. No biggie. Head to home depot get a replacement, and actually the employee was very helpful. I did need a male end shut off valve instead of a female end. At this point I have the main shut off and all the faucets and bathtubs on. My thinking is main is off and no water is running from the valve I just removed from the house pipes, why not turn all the valves off. I do that, come back and check no water GREAT I'll be right back and fix it no problem. I even leave my cell home when I run back to the store. Get home and...
I live in a tri-level house and the bathroom was on the top floor. When I get back my wife says " I've been trying to call you!!! You flooded the bathroom!"
The laundry room on the bottom floor was flood, the bathroom on the bottom floor was flooded, and the vent in the den was leaking water. I don't know how much water was there but at least 2 inches thick, plus all the towels we owned were on the floor.Bad think is, I still couldn't wait to go to my garage and pull the copper and brass from that STUPID SINK.
P.s. Now the hot water hose leaks and I now have to replace that.
