Eight legged visitors

Gesa goes into the bathroom to wash her hands.

"eek, Nick, there's a spider or something just gone down the sink"
"oh, really"
"just come and deal with it"

I go and peer down the plughole and there he is, a little crab peering back at me. He's pretty cute, and I coax him out and try to persuade the family to take a picture. OK, OK, but get up on deck first and don't drop him...

Another of those delights that we didn't get in Cambridge.
