Mostly just to entertain herself, I think. Mom was tremendously creative and terribly mischievous.

I learned a LONG time ago to verify ANY story that she told me that seemed the least bit fishy.
For example. There was a pasture near the end of the road that had a bunch of goats in it. The fence was dilapidated, the pasture had a lot of scrubby trees in it, they got out a lot. That was the only part that was fact.
But Mom would make comments about
the old man who owned the property who had gotten
a couple of goats to keep the brush down. And isn't it a shame that
people just dump goats along that road
expecting that old man to take them in and take care of them. And how sad it is that
they're all on their own now that
he's died and no one is taking care of them. And that I should go get a few so at least those would have a good home.
I would say "Mom, you don't know that ANY of that is true!" and she would say "Well what else could it possibly be, just look at how run down it is. It didn't used to look like that so he MUST'VE died. And the other day I drove by and there were half a dozen goats in the road where someone had just left them...."
Or, there is a house in town that has one of those blue-stripe flags in support of the police hanging in the front yard and a couple of other related things in the yard. When Trooper Walker (who lived locally) was killed a few years ago I wouldn't have put it past her to insist that THAT was his house and for her to try and get me to carry a casserole or something up to the door.
It's NOT his house by the way, his family lives half-way across the county.
She just loved to tell a good story.
