Things That Make Me "SMH"

What does smh stand for? Shake My Head.

I was walking out of Wal-mart and thought about the stuff that people do that make me shake my head at. Here is my top 5:

1. Mobile Drivers
2. People who casually walk across the street and don't speed up
3. People who drive across a full parking lot and almost run into me
4. Rude people
5. People who don't respect other people for no reason

What makes you smh?
