Brownies?

According to wikipedia "Brownies are said to inhabit houses and aid in tasks around the house. However, they do not like to be seen and will only work at night, traditionally in exchange for small gifts or food."

Ever since we moved into this house 2 yrs ago the master bathroom toilet leaked. It's been at the bottom of our to do list and we've been using the shut off valve to keep it from leaking all day.

Now all of a sudden it doesn't leak and I don't have to use the shut off valve. What happened? My kids think it was a house brownie- from the fablehaven books. Perhaps divine intervention? Who knows. I'm just glad it works and I don't have to keep using turning the water off.
