Would you mind cooking yourself while I go answer the door? It’ll only be a few minutes. I just have to get sleep to leave. All you have to do is turn the oven on (remember to turn BOTH dials to turn the oven on and set the temperature), and put yourself in when the oven’s ready. It’s really easy.
PS. If I’m not back by the time you’re ready, would you mind taking yourself out as well? Thanks.
