Seems like you dodged a bullet! How disrespectful to tell you that you do not care about children just because you value your own time! Reality check for this la woman. It would have been hard for me to let this one go. The nerve of some people! You know, IMO not allowing others to try to bully you does not count as unprofessional in my books. I have worked in executive positions in the automotive companies in a male dominated industry. If I would let something similar go I would have been eaten alive. I am almost sure, most male leaders in high positions would not let something similar go (unless it was a strategy). So don't feel bad about it, you stand for yourself. You may have even prevented another daycare provider being bully by this one.
