I said something interesting the other night to Kristi, interesting in that I live by this, but may have never expressed it before. The something is, "You have to interpret my mothers actions through a filter of good intentions. "
She is one of those folks in life some people find annoying. I base this on the experience of myself, siblings, and girlfriends. She means well, I know her well enough to be absolutely certain of that. It's just she asks questions when others would rather not answer them, and she makes statements others might not make, and she has-at times-acted a bit oddly, though certainly never deranged nor dangerously. If you just looked at these actions, you might never see the person inside.
Her heart is good and very willing to share, but you have to look through the filter of her intentions. And if you cannot do that, you may not want to hang around.
