You have had those awkward times in the elevator when no one speaks for approximately 500 floors. It is weird and it does not feel good. So, why not be the bold person who breaks the silence? DO IT!
-There is no improper way to say "Hi."
-You'll more than likely learn something about someone
-Saying hello is relieving....ahhhhhh
-You might talk to someone with an accent -- always good fun :)
-Initializing conversation (AKA, saying hello) raises confidence
-If someone does not respond, just stick your tongue out at them.
So, there you have it. Another day closer to making our society simply.....outstanding.
