Mustathon

A routine conversation with a parent when they suddenly switch to offering unsolicited advice full of musts, shoulds, mustn'ts and shouldn'ts.

Me: Nice weather!

Mum: You should do some work on the house. You must exercise.

Me: (thinks) Shit. This is turning into a mustathon!

-----

Dad: You should get a better job, get a nice girlfriend, learn how to drive.

Me: Oh no! I've been mustathoned!

-----

Me: Was out with the dogs earlier when I bumped into mum. We talked about the dogs a bit then she hit me with a mustathon.
