Have you not heard of the expression “Mad as a March hare”?
You are joking of course!Of course, but I’ve never discovered what made them angry.
American v. British
Mostly…but not about the US/UK difference in the usage of the word “mad.” You folks mean “insane” while we Yanks (usually) mean angry. I always assumed mad hares, hatters, and cows were British.You are joking of course!
