Long time ago I entered a conversation between flatmates a bit late. I thought they were talking about a little doggie, but they were actually talking about someone who was mentally handicapped. I didn't get this until right after I opened my stupid mouth.
Others: "Yeah, but they just behave like that sometimes, you know?"
Me: "You should just put a leash on him when you take him outside. Problem solved."
Others: :eww: :eww:
Me: "Oh.. wait, I think I suddenly need to be out of the house right now." *flees*
