Tam speaks a truth....

Here, she talks about a moment in time. 

Two things I believe come to light in the situation she describes.

Goblins prefer easy targets.  If their intended victim choice suddenly seems less than easy, they will almost always move on to victims that don't make their pee-pee's shrink up.

People who are *aware* of their surroundings, and have *A Plan* for such situations, express a field that Goblins can sense.   It screams in their tiny minds..... "Danger Will Robinson". 

Me?  I generally look like I hate the world and everyone in it... And I'm ready to share my feelings.  

What can I say... it's a gift.
