RE: Alice has 5 ice cubes, Bob takes 3, how many ice cubes does Alice have left for her afternoon Thai iced tea?

I still need to leave my answer even though, lol.
Since the ice container was not mentioned. I therefore specify nil/zero because Bob took 2 in the morning when it was still frosty.
So definitely afternoon there will be change in temperature.

But I love the life lessons behind the question.
