Nod requests a visit to help resolve a problem.
I go round. A friend gave him a small freezer when he came out of hospital. He shows it to me and opens the door.
“There is a lot of ice inside it.”
“It’s a freezer.”
“Can you defrost it?”
“Not yet.”
“How can I defrost it?”
“Switch it off and open the door.”
“How do you know these things?”
