"You Can't Take It With You"

People often say "you can't take it with you." I think it depends on the situation.

For example, yesterday I was at the grocery store and bought some food. The cashier put the food in a plastic bag. Guess what? When I went home, I took the bag with me.

A similar thing happens when I go to work. I like to bring my backpack, so I take it with me.

Now obviously, if I had a car, I wouldn't be able to take it with me inside a building, unless the building had very big doors or walls weak enough that I could drive through.

So, before you accept such aphorisms uncritically, think of some counterexamples.
