You make some good points, but I especially like what y'all are doing for that sick kid. Walking will change that kids life and I think that's something your workplace should feel proud of being a part of.
I don't have my own children, but the family story of my dear colleague since the birth of both children was very emotional for me.
Today, another colleague from the sector, who has a baby child, and who joined the team relatively recently, cried when he heard their sad fate.
Helping others can be rewarding for everyone involved, the helper and recipient.
