Not sure if it counts as a Spot* but: Condor2378, as I was helping his distraught offspring remember that a 'missing' gym bag had in fact been deliberately left in the classroom.
I told him it reminded me of the time I spent 45 minutes looking for a BB tool that I had forgotten I didn't own because I'd borrowed the one I used last time.
He then asked if I was on CCE.
Yeah, I guess that kinda anecdote makes that a solid guess.
*was a pre-arranged meet since child collection is part of the routine, or does the fact it wasn't arranged as Condor and Uberuce mean it's a Spot? Spottington Crescent rule vultures: attack!
