There's one uncle who brings sodas, ice, and cups. It's fine.

Sugar and salt are in totally different packaging types. If I try to work in an unfamiliar kitchen and they have a paper bag of salt, then maybe I'd mix it up.

I have mixed up teaspoon and tablespoon before. That was unpleasant.

"Problematic" but your face is the O?

I saw this sign at the LA County Natural History Museum a couple of days ago.
