Easy question. Society used to ALWAYS be based around a certain generation (ie: The most famous generation that influenced society being the hippies and their movement.)

Owls are nocturnal. When they fly, they don't make any virtual noise either -- and thus, sneak up on their prey. Their heads also spin 'round completely.

Forget which it was and I am sorry for this but if you see an owl during the day, it's either good or bad luck. Like I said, I forget which though. Sorry again.

Read the directions on the side of the box. It's not hard.
