What are some things you find strange that are normalized in society?

I'll go first. I've been drinking dairy milk my whole life and using it in foods where necessary, but I always found it strange that we drink the milk from other animals and not our own species. Don't get me wrong... I find the thought of drinking a random woman's milk disgusting, but I do find it strange.

And don't get me started on the government and system.
