I have always said this! Joey and my sister can attest, if they ever ask my opinion on what they are wearing or something, I will say, "No one is looking at you." My sister says I'm rude, but its so true!
This is also why I never let myself get embarrassed about anything, because I know everyone is more worried about themselves than what I'm doing.
