Some of my relatives can be quite frustrating when it comes to little things.
For example, some of would insist on referring to carbon dioxide as "carbon." It's enough to make a chemist cry.
When playing chess, they would refer to the knight as "the horse." They'd refer to the rook as the "tower."
Oh, and playing cards with them made me cringe. Remember the old familiar suit of clubs? They'd refer to the clubs as "clovers."
Good freaking grief.
