Among the many joys of parenthood is being the assigned chaperone for your kid’s class field trip, and by “joy” I mean “misery-inducing hellscape.” Sure, you love your kid, and maybe you even like some of their friends… but a whole bus full of kids, excited to be doing something out of the routine? That’s sure to send even the most patient parent into a minor bout of insanity.

If you don’t believe me, ask Simon Smith, a dad from the U.K. who recently accompanied his daughter and 59 of her classmates (yikes!) to the Kensington Museum. Along the way, he provided regular Twitter updates on the nightmare that was his day.

This is Simon Smith, a loving dad who volunteered to be a chaperone on his daughter’s school field trip.

Even though they were told to use the toilet before the trip began, kids are kids.

That’s when the real nightmare started to unfold.

Even his daughter turned on him.

Then, there was puking.

Possibly the worst part, however, was the string of neverending questions.

Things didn’t improve upon arriving at the museum, either.

Simon made sure to document the many gems the kids said to him.

Here’s how he described his ordeal to his wife:

Then it came time to visit the gift shop, which was also predictably disastrous.

The return trip was also horrible.

His final tweets pretty much summed things up perfectly.
