She has so many, and I dunno why this is the one that comes up first in my mind, but she always says “if you can’t open it, you don’t deserve it.” This phrase (which sounds a bit more whimsical in the original Serbian) goes for everything from bags of chips to those plastic packages school supplies come in. She shows no mercy when something’s really hard to unwrap or pry apart.
I have subsequently gotten very good at opening hard-to-open things, and am now the go-to pickle jar guy. -etymologynerd
