Why do all our emergencies happen at night?

Last night, as I was preparing to head off to bed at the ripe late time of nine o'clock, my husband noticed that there was a small waterspot on the kitchen ceiling. Now, this would not be disturbing to most people, but as I have a two story home, and my laundry facilities are on the top level...this was a big deal in the Johnson household last night.
So, I went upstairs to check it out. I did not see any water at all in the spill pan that the washing machine sits in. In theory this pan is a great idea, and should prevent leaks from seeping through the floor to the ceiling below. Yeah, that's great, but what about the leaks that aren't from the machine, but rather are from the pipes themselves? You guessed it, that's where our leak last night was coming from. So of course it dripped down the inside of the wall and through the kitchen ceiling. It wasn't a huge leak, but it was enough to be a major problem if left unattended.
So as I was trying to determine where exactly the water was coming from, dear husband...who hereafer shall be referred to as Mr. Fix It, was cutting a hole in my kitchen ceiling. Just a small hole, but a hole nonetheless. Now, in addition to the leak, we also have a hole to patch in the ceiling. And of course, once it's patched the entire kitchen ceiling will have to be repainted, as the house is almost four years old and that one spot of fresh paint will stick out like a sore thumb if we don't do all of it. Did I mention that the kitchen ceiling is huge?
So the valve upstairs is still leaking, so per my father in law's advice, we turned water off to the laundry machine. Only problem with that idea is that to turn water off to the laundry machine, you have to turn it off to the whole house. So every morning when we leave for work, we have to shut off the entire water to the interior of the house so that if the leak "gets worse" it won't flood everything. And every evening when we come home we have to turn it back on to shower, toilet, drink, and wash dishes. Very convenient.
Hopefully we'll get this problem taken care of within the next few days and things will get back to normal. On the bright side, I guess I could just look at this as a much needed break from doing laundry.
