1. Bert is very careless and forgetful
2. I am an expert plantswoman
A few months ago Bert was in a tizzy because he had lost his shallot bulbs. He searched the house high and low. He asked me if I had seen them. "Me?", I answered him. "Of course I haven't seen them. That is just typical you leaving things at your arse then not being able to find them when you want them."
Today he said to me,
"I have solved the mystery of the shallots."Sure all's well that ends well. Isn't it?
"Oh. What happened to them?"
"They're coming up nicely among the tulips you planted."
