Alea, I asked for the fire crew to visit my parents to review safety at their home. Dad smoked a pipe and often fell asleep in bed when doing so. He had a bedroom downstairs because by that time, he was too frail to go upstairs. Mum had lost hearing and sight and slept upstairs. You can imagine our anxieties.
The fire crew arrived in their red engine. Initially dad was mortified on a 'what will the neighbours think' level. He'd been in a similar disciplined, uniformed service and within minutes the two lovely fire crew were drawing war stories out of him. They were so helpful, fitted fire alarms and gave excellent advice.
When working with vulnerable children, we often arranged visits to our local fire station. The crews were universally brilliant with the children, allowed them to clamber over the fire engine, and rattle the bell. Great workforce frankly.
