Swimming in my Pants

The last time they forgot to pack my swimming trunks
I went in the pool in my underpants.
I don’t think anyone noticed, apart from me,
but trunks are a basic requirement. Absolute necessity.

So, just to help out, I made them a list:
What do you think? It goes like this:

Trunks, clean pants, towels.
Shampoo, clean socks, goggles.
Locker coin, cash for a snack -
this is what you need to pack.

It didn’t go down well. The reason I could tell
was they took my bag down from the shelf
and said:
Think you’re so clever? … Well pack it yourself!

(At this point I thought I’d better back-track -
if only because they pay for the snacks!)
