I finally (reluctantly) answered this call.  It was from a breast cancer research organization, to which I had made a contribution in 2012. The caller was very polite and was just soliciting another donation for this year.  Useful tidbit for others who may receive this call:  I told him that I had changed my approach on donations to breast cancer research and instead of donating directly to the organization, I was contributing toward friends' personal campaign efforts.  (It's true!)  He thanked me and the call ended in under two minutes.
