Tibby the Valiant

Tibby and I just got back from our last walk of the day.  We just took a quick walk down the street and back. 
On the way down the street we passed a neighbor talking on his cell phone in his driveway.  On the way home we passed the same neighbor, but he stepped out from the shadows toward us, he was carrying a bag and some kind of stick thing to put in his garbage.
Tibby went NUTS.  Growl barking, lunging and howl barking.  It's hard to describe the way Tibetan Terriers bark - it's not like other dogs.
She was very scary. 
I didn't encourage her, but this is the sort of situation were I would want my dog to bark.  We just kept moving and I didn't say anything to her.  I said sorry to my neighbor, but really I wasn't sorry.  Who comes out of the shadows carrying a stick at 11:30pm!?!  Serves him right!
I usually complain that Tibby is too friendly with strangers.  She has always been especially friendly to men.
