My Nemesis

Did you know that squirrels make noise?

Until recently, I didn't.  But lately, every time I'm out in the yard, this squirrel keeps chattering and hissing and making all kinds of noises while staring directly at me.  It's starting to freak me out a bit.

Do squirrels ever attack?  I don't think so, but then again, I didn't think they made noise until recently either.
