That is a GREAT story! Good for you, stand up for what is right!
I experienced something similar when I helped organized five of my high school reunions. I missed my first 10 year reunion because I was in the military but got involved to initiate the 20th. Initially, I was disappointed that I, and several others helping, were only able to locate less than half the class of 610 people. And of that group, only 150 or so responded wanting to attend. But I finally decided that the reunion was to be planned for those who were attending and not to be concerned about those we couldn't locate or didn't respond to the invitation. That reunion, and over the next four reunions I was involved in, taught me that there was a consistent number of people who were interested and the others
Put the party on for those who are at the party and not to worry about those who are not there. Success in life is for those who participate, not for those who chose not to.
