What random situations do you think are awkward?

For example:
Being in line at the supermarket and seeing a toddler scream and throw a tantrum.
Long pauses during the middle of job interviews.

Accidently farting in front of someone you like.

Walking into a room at work as a co-worker is leaving and smelling the fart they just left. That just happened this morning Mistaking someone for the wrong gender. Congratulating a fat woman for being pregnant. Having a co-worker know it's you in the stall and you can't do your business quietly.

Talking about someone & then finding that they're standing behind you.

I think it is really awkward to get to the door of a business and have that moment where I don't know if I should move faster, and hold the door, or back off for the door to be held for me. Had that happen this week at the gas station going in and out. Both times, it was young men, and I sped up and held it for them, and BOTH looked a bit annoyed.
