My mom is driving 30 km/h on an icy road. Me: Mom, you can go a little faster. Mom: No I can't. Me: Why? Mom: Because, we'll hit a patch of black ice, we'll flip over a dozen times, land in the ditch, and we'll be dying on the side of the road. Then people will drive by and point and laugh like HAHA! Do you really want people to point and laugh at us?
