Burning questions

If no one was in a forest and a tress fell, would it make any noise?
Is the glass 1/2 full or 1/2 empty?
Why do store that are open 24 hours a day have locks on the doors?
Why are manhole covers round?

1)yes it still makes a noise,it just means no one was around to here it.
2)Wichever one you prefer.
3)Because some 24 hours stores close on holidays
4)because they didnt want it to be square or a triangle..Is that so bad?

Nope...without sound vibrations reaching your ear, there is no sound

It's 1/2 full...nothing can be 1/2 empty

Power outage = security

They are less likely to buckle and stick out like the corners of square ones would do...they're stronger under the weight of vehicles.

those questions frustrate me

the 24 hour open stores are required by law to have a locking door.
and half full, half empty, depends on your point of view on optimism and pessimism

I think the half full/half empty question depends on whether your working towards emptying it or filling it up
