Questions

Today I thought of a question. A few questions. A few difficult questions. Questions which seem un-answerable. They are all related actually

If someones screams in a deserted place and nobody is there to hear, is he considered making noise?

Or if a tree falls in a jungle and no one is there to hear it, is it considered causing a loud sound?

How about the phrase "wasting your time"? If you played video games for the whole day but managed to achieve a high level or high score, is the time used considered wasted when you could have done something else like house chores?

If a person jumps into the water and swam for three seconds before stopping and just float himself in the water, is he really swimming?

Let's see if you can answer them
