Call daycare to tell them CH wasn't going to be attending anymore?? My goodness...I was thinking more along the lines of reaching LH, or someone close to her to have her contact him as soon as she arrived, etc., etc.
What you expect from people is not always what you're going to get!!! Men have a tendency to handle their anxiety/depression by getting angry--cursing at a cop doesn't give me a sense of hidden meanings or ulterior motives, and was not out of the realm of reasonable expectations in this situation, IMO.
BTW...the witnesses said he had asked one of the first people who came over to his car when he stopped to call 911. I would have felt an URGENT NEED to contact the mother of my dead child in that situation...and would have had a HUGE problem with anyone who got in the way of that. Because he didn't fall into the expected heap-on-the-ground doesn't tell me that he wasn't totally freaking out--he saw his son, he knew his son was dead, and he freaked out. So much so that he had to be restrained by cops.
But, at the end of this day, we're all forming theories--theories based on small bits of information molded to fit our perceptions of what really happened.
