Simple question (no, it's NOT homework, I'm no longer in school.)
If "Tina" takes something belonging to "Zoe" - be it money, an umbrella, food, a car, clothes, or toiletries - without permission from Zoe... even if "Tina" intends to return it later. Is it "borrowing" the item, or is it "theft".
I feel if you are borrowing something, you've gotten permission of the owner of the object to use it, and return it, in similar condition to what you took it.
Taking it without asking, and returning it later, I think, is still theft, as you didn't have permission in the first place.
To be clear: taking something without permission (no matter the size of the object) - is it "borrowing" or "theft" discuss!
Edited because Neowin doesn't have polls.
