Just agree (that awkward moment when)

We've all been in this situation. It's really awkward. You're just sitting there pretending to know what they said.

But in reality, you have no clue. You're just completely clueless, but you just agree anyway, just to get the conversation moving along.

This is relatable

If they realized you had no idea what they were saying, that would be even worse. I think we've all had moments like this. It's sometimes hard to listen to everything someone says. You try your best, but it doesn't always work that well.
