It's actually one of my 180's to be doing the gratitude thing. It's what I discussed with my coach. And he actually suggested the explaining the reasons behind it to her, because he knew it could be annoying.
It is both for me, to grow as a person, but also because there are people who are deserving of appreciation and I have not done well in expressing that. I know I have appreciation, I feel it, but the person I have gratitude for does not. Or if they do, they get it all at once on special occasions, and not consistently.
She hasn't been annoyed with all of them. It's possible my timing was bad. The time that she seemed most annoyed, in particular, she was already frustrated with our daughter when I brought it up. Today I thanked her before leaving for work, and before explaining anything to her, and she was more pleasant about it.
