Ruth, although I completely agree with you in all points, I am of the opinion that keeping that "tab" you allude to ( when you say that certain people came to expect things from you), is waaaay too much effort and mental strain for me. As I see it, if I feel like doing something good for someone or if a person asks me for a favor, I would do it (or not do it), based on whether I am willing and able to do it. It is too overwhelming for me to start "pulling the file" on that person and decide whether he or she deserves it. I honestly don't want to be bothered. Again, too much to worry about that way. I know it is a much different way of seeing the world, but you guys know I'm a bit odd.
In this case, Mochi is giving out unused items, which I really see as a win-win situation. When I want to get rid of something, I just want it out of my sight. I am usually the one thanking the person for helping me get rid of my clutter, LOL, go figure.
The dinners, gas, car, et al... ah, who cares? I know when I was bed-ridden with horrifying panic attacks, none of that mattered. I mean, look at all of the people here, who in this very moment are facing significant health and physical struggles. I am not trying to be dismissive. I am just trying to say that one should be thankful when life is so darn good, that stuff like this is the only thing to worry about.
