It didn't rain today, so I didn't have to work. Why don't you have to sit around and wait until it rains?
I'm also not going to explain something just because I said it in a rap. Take what you want from it.
Isn't it true that the fault of birth rests somewhat on the child? I believe it's we who led our parents on to bear us, and it's our unborn children who make our flesh itch.
