NOTE TO SELF: Never let a seven-year-old pump gas, even if he claims to know how to do it. Even if he tells you "Gram let me do it before." He is not trying to be a gentleman or a "good little helper." He is lying. Believe him, let him do it, and you will end up with a kid soaked head to toe in petrol.
2nd NOTE TO SELF: A seven-year-old boy is unpredictable. He may, without warning, pull a pump out of the gas tank while still squeezing down the handle, then wave it around—eyes wide with surprise—as gas showers upon himself, his mother and their car in a Zoolander-esque "gas fight" montage.
4th NOTE TO SELF: When you get home, do NOT attempt to wash gas-soaked clothing in washing machine. It makes your washing machine (and all future loads) smell like gas.
5th NOTE TO SELF: Do NOT put just-washed-but-still-gas-soaked clothing in the dryer. This may start a small fire.
6th NOTE TO SELF: When you Google "how to get gas smell out of washing machine" and it tells you to put a vinegar and baking soda mixture into the wash, use caution when adding the baking soda. It will cause a chemical reaction of foam to shoot up rapidly into face--burning eyes, and peppering the ceiling and floor with Eau de F'ing Vinegar.
7th NOTE TO SELF: Give up and open bottle of wine to block out home and child that smells of gas and vinegar.
