When you see a guy/girl smiling and waving at you at the same time, he/she likely wants to get you dead in a hurry. Especially if it's not a wave goodbye.
First the media said a second wave was coming in the fall. Then they said the United States had already begun a third wave. At some point, they just start saying another wave. They must think it's hilarious.
If it's still the second wave, the third wave hasn't begun yet. Some people do pay attention.
When you don't want to deal with somebody, don't wave at them, don't make a peace sign with your fingers at them. Quit being a fuckin moron and fucking with their life and their neighborhood.
