I know we all have them.
My wife's is when someone says, "John, that does the drawings." Her comment is John is a who not a that. "John, who does the drawings."
I have two.
Ending a sentence with a preposition even though I do it occasionally.
The use of "Me" and "I".
"John and I went to the ballgame."
"Would you like to go to the ballgame with John and me."
The sentence would read correctly if you would use "Me" or "I" without the other person. Fairly simple really but so often done incorrectly.
