You're running down the streets because your late for something, and you start to slow down because there are two people in front of you walking REALLY slow.

You're still politely walking behind them, not saying anything.

You: WALK FASTER, GRANDMA!! I NEEEEEEED TO GET IN FRONT OF YOU!!! MOVE IT, MOVE IT, MOVE IT, MOVE IT!!!!!!!!!!!!! COME ON!!!!!!!!!!

*Keeps walking behind until they turn right, then sprint to your destination*
