closed mouth

I was recently held responsible for 2 mishaps that happened at work.Now normally I would go and convey my displeasure with the unfair situation however this time I chose to keep my mouth shut.
The first instance is I failed to put  a block between pallets, and when the driver had to brake hard the pallet fell over and caused a spill. The second instance I couldn't finish loading a truck so I put the paperwork back in the slot for the next crew to finish. The supervisor couldn't find the paperwork and the truck was late by 30 minutes.He said I hid the paperwork so it would be late.
In the first case I should have put up the block however I'll only accept 40% of the blame because I wasn't driving.In the second instance I could have told him on my way out about the truck then he would have known about it. However all I feel I'm negligent in the second case is my failure to tell him about it because I put the paperwork in the correct location.
The reason I'm sharing all of this is because normally I do go and vent my displeasure with the bosses.
This doesn't work out for me and I usually make it a lot worse.This time I spoke only with my supervisor and she helped me go through all the scenarios and helped me see how things went haywire and I just happened to be the unlucky person caught in the situation. So for once I feel better because I was able to let all the hot feelings die down and looking at it objectively.  I can improve in these 2 areas. I feel I am finally keeping my mouth shut at the appropriate times and found a more constructive way to deal with the situations.
What this has to do with Kung fu is this. I am 100% responsible for my actions or lack of action. By keeping a cool head and not blowing my stack I was able to take the criticism and use it to improve myself.
I did dishes, took out the garbage, swept the floors and made the bed
Had steak and tortellini for supper with a salad. had wonton soup for lunch and had a banana and an orange for snack and a granola bar.
