Hee! Ok, well lets start here, what sort of organization do you want to help with? Animals? Homeless? Elderly?
I would love to do something with animals, but I can't. I would either be horribly depressed or I would have 55 cats and 34 dogs.
I used to do some literacy tutoring, but that is so regimented in that you are assigned to a specific person and you have to meet with them X times per week for X amount of time. While I have time on my hands, I can't get that regimented as there are times when I travel and have to be more flexible about work. I am not good with kids, so that is out. Gah --- maybe I am useless to everyone.
Or just too picky for my own good.
In my defense, a LOT of the stuff I am seeing takes place during the day. Um...people have jobs. I can't just disappear during the middle of my work day! I suppose that kind of thing is good for retired people, but not so much me.
I just need to keep looking.
