As the parent in our family who has the shortest fuse, this really got my attention. I have heard that story before, years ago. But, now that I have a six year old and a rapidly approaching terrible two, I think I need to really pass that one along to my kids.
The older I get, the more mellow I get. I'm not a hot-head, but I do let my anger get the best of me sometimes and I get snippy or shout unnecessarily. It is just not worth it though in the end...nothing is worth the damage harsh words said in anger can do.
