If you need convincing [insert joke about this being a big if], I submit two examples from yesterday as supporting evidence:
1) When I turned on Kira’s oven to cook the turkey, I turned the temperature dial to where 175C is on my oven dial. Which is not 175C on her oven dial, but 150C. I realised after about an hour, but it was enough to balls the timing up and dinner ended up being an hour late.
2) I picked up a dish that had just come out of the oven with my bare hand, and burnt my thumb quite badly. Which meant that I couldn’t put down the cold beer I was using to ice it, and had to eat dinner with my left hand only…quite difficult!
I rest my case.
