When conga lines go bad

I was walking up Calton Hill today with the siblings and one of the parental units when we saw this nugget of industrial strength unusual headed in our direction. Thirteen blindfolded randoms following one standard-issue random. All very random.

Person A: Hello.
Person B: Hello to you too. Lovely day!
Person A: It is indeed. What have you been up to?
Person B: Oh, just some gardening. You?
Person A: I went for a lovely walk.
Person B: Wonderful. Where did you go?
Person A: Well, to be perfectly honest, I have absolutely no idea.
No, I really can't help you with that. All I know is that there was walking and then............then......... nope it's gone. I only remember the walking bit. Nothing else. Sorry.
Person B: I see ................................... Well it's been great talking to you. I'd better get back to the garden pronto.
Person A: Oh, okay.
(Person B runs away)

I think they belonged to the lovely people performing Tai Chi in red jumpers further up the hill. All deeply groovy.

Toodle-pip.
