Cycling home along a secluded footpath in a dodgy area of London. I saw two adults (man and woman) who looked rather shifty. They gave me a guilty look and said hello as I went past (odd to talk to strangers here).
I saw one of them had a pipe partially up his sleeve. Would this be a crack pipe? It was clear, so definitely not a tobacco pipe. What is is smoked with a pipe? Or what else could this be.
I realise I'm pretty naive. I'm just wondering if I should stop cycling this route. It's nice and peaceful and away from traffic though.
