Can't We All Just Get Along?

My next door neighbor calls Sasha, Beer Keg. She doesn't mind. She waddles over, wiggling, and waggling, all happy to say hello and get a belly rub. That's the great thing about that girl, no matter that she's had three owners, she is still an extremely friendly dog. When we do our morning walk she goes into a frenzy of cuteness when another human is out there. She likes the other dogs, but it's the humans she is excited to see.

Yesterday morning we came upon some new folks, a man and a woman walking their large pit bull. Sasha got excited so I started to ask if the pit bull was okay around other dogs. The man smiled, but before I could get all the words out, the woman spat back, "We're pooping, go away."
At that point the man took the pit bull behind some bushes, and Sasha continued trying to pull towards the woman, wiggling and waggling.
"I said we're pooping over here."
"She just wants to say hello... "
Before I could finish saying that she wasn't going to bother the pooping dog, she again sneered and screamed at us.
"I don't want to say hello!"
I pulled Sasha away, and mumbled something about the woman being quite unfriendly, and somewhat of a...  well let's just say it wasn't a nice word.

It's probably a good thing Sasha didn't get to say hello to the pit bull. No need to make friends with a vicious bitch, or her pit bull.
