I have negative free time these days, so the only organization where I volunteer my time is my synagogue.
I donate money annually to my synagogue (over and above dues), AEPhi Foundation, my alma mater, and the local police and fire departments. I've also donated when natural disasters such as Katrina have occurred. I also donate clothes and books when I clean out my closets (which I don't do as often as my husband would like

).
