Every time one of my friends announces yet another pregnancy I internally scream because it means more years of them being extremely boring to hang out with, as they literally have nothing else to talk about or the kids are there too and we have to amuse them.
I get this, but kids can also be amazing entertainment. In addition to being cute, their complete mystification at how the world works makes for the most surreal humour. It's an acquired taste, but worth picking up.
