If you’ve got to have a child home from school who’s not poorly (but has to be home because he jumped around too much straight after lunch and made himself sick), then I would definitely not recommend taking them shopping so you don’t have to go in the evening.
However, if you are foolish enough to do that, then I would thoroughly recommend ensuring that it’s an 8 year old boy with a passion for animals.
Take said child to the library first, and take out a book about animals. He will then read the book to you as you’re shopping (narrowly avoiding walking into all the other shoppers), making it an interesting and informative shop for both of you.
As you can see, this was at the beginning of the shop.
