Listen to me, you new generation of elephantine-sized backpack people: when you wear a backpack that’s large enough to fit only one of them in the cargo-hold of a plane, you need to be more aware of its presence while wearing it. When you turn your body while wearing that monstrosity in a crowd of people, IT SLAMS POOR INNOCENT PEOPLE WHO’RE MINDING THEIR OWN BACKPACK-LESS BUSINESS. And it’s USUALLY ME!! Thank you so much for your cooperation.
