Have you ever watched an ant crawling and wondered how far away it is from its colony?

What if the ant was crawing into a trashbag last week, and it got taken out in the garbage and ended up in the dump. Then it realized it was far from home and started trekking (I don't know how to spell that) back home, and it's in the middle of this fantastic journey when you see it! Maybe it knows exactly where it's headed. Or maybe it hasn't the foggiest idea, but he/she/it will stop at nothing until he/she/it is satisfied!
Or maybe it's 5 inches away from its hill.

I like to think it's the first one. :]
