What's your dumbest reason not to have kids?

To clarify, I believe any reason not to have kids is good enough of a reason. Not wanting them is enough reason on its own and you're not owed an explanation to anyone.

This is just for fun. So, among your reasons not to have kids, which one do you think is the dumbest or shallower?

I'll go first: you have more chances of getting lice if you live with a small kid. I don't want lice. Those things were a nightmare my whole childhood and I absolutely do not want to deal with them now that I'm an adult.
