Loose vs lose
Loose - This shirt is loose on me. I need a smaller size.
Lose - I don't like to lose; I love to win.
I'm from Louisiana, so this next one is constant.
You
You - Can be singular or plural. There is no need to say "y'all" or "you guys" to include multiple people in a statement. The worst is when people say, "I was looking at you guys' stuff."
