Normally I'm a very self-sufficient person. I own a power drill and other tools, and I put together most of my IKEA furniture on my own (my dad put together the end tables in the living room because he needed a project, and the kiddo's mirror required a second set of hands for measuring). But what I cannot (will not?) do is drill above my head. Especially not in the ceiling.
A friend is visiting, so I set him to work after Shabbat ended. He drilled three holes in the ceiling for me to hang some lamps from IKEA. And then he identified the location of the leak in my sink, which I could probably have done myself but haven't bothered with.
And this is why it is good to have a man in the house.
