Silently judge their entertainment choices. If they watch FauxNews, turn the volume down to whisper, or change the language to Spanish, or change the channel to Sesame Street.

Food packages that are resealable but the glue they use is to adhere the seal zip to the bag is weaker than the seal. So when you go to re-open the seal, the seal zip pulls away from the bag and there goes the resealable feature.

Those stretchy b******e seals on some condiments, e.g. ketchup, that doesn't allow anything to come out of the bottle until you're squeezing it hard enough to drown whatever you're trying to put the condiment on. "Oh, you wanted a thin line or a small dollop? Best I can do is half the bottle...".

Why the hell does my stove / oven / microwave not have a battery in it that can withstand a .008 second power outage so I don't have to reset the time?

The seal on bottles that has that itty bitty piece of plastic you’re supposed to pull to get it off. Absolutely never works. They should save the plastic and just have us do what we’re going to do anyway.

Shampoo bottles that flip open so easily in luggage but NEVER when you’re in the shower with slippery hands.

The ‘push here’ perforated part of a cardboard box (like a box of kosher salt or corn starch) that NEVER works and instead just dents the box and makes it even harder to open.
