Who is?
Some friends have a peculiar way of expressing their love by teasing each other. It’s not everyone’s style, but it’s all in good fun. However, if you tease your best friend, sister, or significant other, you better get it right and not give them a chance to turn the tables.

You might call this karma – this girl arrived at the airport to pick up her friend with a sign reading “idiot,” and by holding it upside down, well, it’s clear who’s the “idiot” in the situation. It wouldn’t have been so funny if it wasn’t so ironic.
