Come on, we all do it. I’m always on the lookout for new material, so please share away. Some of my favourites:
Narrating my performance of mundane household tasks via the medium of song
Answering questions that she is asking to other people while on the phone
Deliberately picking stupid cutlery, eg asking “do you want a fork or spoon?” and then putting a massive wooden fork from the salad tossing set next to a normal sized stainless steel knife
Writing ridiculous made up things in the middle of the shopping list
and so on.
