I am a member of a gym.
There are 6 parent and child spaces. I take the children most days.
One day, I took them, took DD swimming and then met DH who took both children off my hands and I went home before them to sort some bits out.
Returning to my car (without children) in the parent/child space I was "tutted"
at by a woman waiting with kids in the car. There were other spaces near by.
Would I have been unreasonable to give her an earful of how I had had 2 children for the afternoon until mere minutes ago.
Instead, I blushed, head down, got in to my car and drove off. I remain annoyed about this, but am laughing at myself as I type!
