Here’s something I find cringeworthy for no good reason.
You’re driving somewhere (usually to or from work) and you pull up next to someone you know. There’s the initial excited wave, “Hey!!! Oh my gosh I know you!!! Hi!!!” And then what? When you’re actually driving it’s no big deal, you wave and keep on going. But when you’re stopped at a light, or even worse – traffic, then what? Do you look straight ahead? Fumble through your bag, tappity tap on the steering wheel…eeek! I hate it!
