I was once a very angry human being and knew that i had to own the anger rather than blaming on the idiots and evil folks who made me mad. The targets included my spouse and children. I thought i had surrendered that anger long ago. I know the difference between giving up anger and stuffing it and was pretty sure that i had done the former.
I also totally ignored my "ninety second rule" which says i wait a minute and a half before responding to a negative stimulus (although i do allow myself to move out of the way of falling objects). At least i was almost immediately aware of my outburst and did not have to have it called to my attention by someone else (which was once the case). It has been a very long time since something like that has happened and i hope it will be a very long time before it happens again.
