I can be a grammar nerd, oh yes. :-) In fact I made an error in my first post here on Steemit and I have not yet edited and corrected it!

When I was a schoolboy, I used to walk past a Dentist's Surgery on my way in to school. In the car park was a sign. The sign read 'Dentists Patient's Car Park'. I walked by it for years grinding my teeth at it. Only one patient for all of the dentists, and an entire car park to themselves!

I walked on by... until the day I snapped and scratched off the offending apostrophe. Then I added an apostrophe in the correct place. Or so I thought. It dawned on me then that I didn't know if there was only one, or more than one dentist working out of this surgery.

I didn't feel confident about walking in and asking for clarification about the sign that I had just willingly defaced. So I left it and went into school.

At the end of the school day I walked by and saw that someone had scratched out the word 'dentist' entirely. The sign now just said 'Patients' Car Park'.

That was not the end though.

A week later, somebody else had a go at the sign. They were obviously baffled by the apostrophe. So they had removed it and the 's'. The sign now read 'Patient Car Park'.

We left it at that. And every day we used to smile as we went by such a virtuous car park.

So yes, I have always been a grammar nerd.
