I spent the lunchtime making some urgent child and adolescent mental health services referrals for children, and it was late in the afternoon when I left for a home visit in an unfamiliar part of town.
The sun was out and an ice cream man was selling lollies to a herd of little children across the road. I negotiated my way through the recycling and towards the keypad at the side of the door. I looked around, carefully checking that nobody was near before quickly keying in the numbers.
'I'll watch your car,' said a voice behind me and I turned to see a teenager loitering on the footpath. He was perched on a skateboard with his hands poised to spray some graffiti on the fence, which already boasted 'Banksy woz ere' in bold letters.
'That's very kind of you,' I said, turning around to smile at him. Obviously, my first impressions were misplaced - he was not up to no good, after all.
'For a fiver,' he added.
'Sorry, but I've no money on me. My kids took the last bit of cash I had this morning for their snacks. How about some free medical advice instead?' I suggested.
He seemed to think this over.
'Do you have any chlamydia kits?' he finally enquired after some consideration.
I eyed him up and down. He looked about 15.
'How old are you?' I asked suspiciously.
'I'm 14 next week,' he said and grinned widely.
'No way! You are not in the 15-25 age group to dispense chlamydia kits, let alone even know about chlamydia.'
'Oh yeah, I forgot that nobody gets chlamydia outside the range,' he said, looking at me in mock horror. 'Actually, they're not for me; I was going to sell them at school,' he added.
'Even worse. Definitely not!' I shook my head and made my way inside, leaving my car and the aspiring entrepreneur in the hands of the gods.
