Discussing a computer trolley with H as our current arrangement is a PITA so we need something on wheels. Fairy Nuff, conversation rolls to a natural stop after agreeing where it will go and what we need.
Then....
"I have found one that is 46 cm diameter and 71 cm high"
me - "Diameter? Thats a bit odd, dont they mean width?"
"No, diameter"
follows lots of discussion about width v diameter and it turns out that he is talking about the Ali Baba basket we need for the laundry that we were discussing yesterday!
Apparently IABU to not have understood that! I said that he could have mentioned he was talking about the basket and he said that it was obvious!
