Shapes

Today I was supposed to leave a little early so Kate could get to her book group. I got the grille up, the sign in and half of the storm doors closed. As usual in these situations, someone came in.

'Hi, the museum sent me down here, because they were too busy.'
'Oh, right. Okay.'
'Here, look.' He pulls a stone from his pocket and hands it to me.
'Look - here - a face. With one of those... you know. Like this.' He gestures.
'A ruff?'
'Yeah. And a big collar, look.'
'Mm.'
'And here is another face, a bit smaller, in this shape... here. You can see it better if you wet it a bit. See?.'
'Okay.'
'Look on the back. It looks like a number.'
'I don't... I can't... really see what you mean. I think it's igneous. A volcanic rock. You don't get... fossils in igneous rocks, though.'
'Do you not see what I see?'
'No. No, not really. Sorry.'
'I have another. Here, look at this.'
'Well this one looks like a piece of ironstone nodule I think.'
'Not a meteorite, you don't think?'
No. Sorry. Look, I really have to close up now. Sorry I couldn't be more helpful.'
'Ok, no problem. It's just the museum folk sent me down here. Too busy.'
