I pretend I do not see
You act like you're blind and don't want to get involved in whatever mess is happening right in front of you.
My cousin spilled his lunch on the floor and I pretended I didn’t see it. I didn’t want to be the one to clean it up.
I saw my friend cheating on a test and I just stared at the ceiling like I was dead.
My dog peed on the carpet and I said nothing. I was a ghost in the house.
