Not breakfast

Walking to the shops at lunchtime I came across a colleague and an ex-colleague chatting on the corner. I joined in. Because they were talking about the etiquette of defriending people who post pictures of their breakfast on Facebook and I had my camera round my neck the conversation turned to blip. J seemed very interested as we headed towards the shops and I told her how to find me here. Then, suddenly, I had to find a way to let her carry on without me. How do you explain to someone who’s up to here with pictures of bacon and eggs that you’ve spotted, ahem, a bus-stop shadow with orange?

Sorry, J. You’re allowed to walk away now, no questions asked.
