For those who don't know, my mother Dot works in a pre-school nursery. Every so often they have a week of 'people who help us', to help familiarise 3 year olds with (amongst other things) the 999 system: what do to when someone is hurt or they're lost- that kind of thing.
Anyway, my involvement is this is the following. Seeing how I work in the police, and my mother works at the nursery, I go in for a morning with most of my uniform and kit. On this occasion, I walked in whilst they were still in their constructive play time. The idea was to familiarise them with the sight of big adult with strange yellow jacket and strange things on belt, so they wouldn't be as intimidated should they ever need a policeman.
So:

I swiflty became the centre of attention for the more confident ones

I was wearing my own flat cap when I got in. However, that swiftly got taken off me:

My hat proceeded to be put in their (pretend) oven. Thats why I couldn't wear it the rest of the time- it was too hot, you see- silly man, can't wear a boiling hot hat
Once their play time was over I was 'formally' introduced and I sat with them and explained with the help of the leader, what I did and what the various bits on my kit belt. Radio and torches are easy to explain but they had an edited version for handcuffs (sometimes people get angry and do something naughty, and have to come with us to the police station) and baton (only used if somebody is hurt inside a house and I need to break a window to get in!). Incapicitant spray was left at the police station in london. 15 3 year olds and CS spray are truly not a good idea.
One day I might speak to Herts police and see if I can borrow one of their cars so I can show them the flashing lights and all that. A simple idea in principle but bound to be fraught with difficulty knowing job politics!
