I am glad I did not send that angry email

I am happy that I did not send that angry email.
It was past 10 pm in the office.
Something I did in good will turned against me, and I thought this person was being deeply malicious with me.
I felt so wronged when I first knew. Poured down the anger into quite a long and heated email rich with sarcasm which then felt somewhat professional. I also made sure to CC everyone who I think should know of this behavior.
My mouse cursor was hovering on the outlook send button.
Then at the very last moment I decided to send it to my private email inbox rather than to that colleague. All the passionate writing has somewhat calmed myself down.
After few nights of good sleep, and complaining a ton to a few good friends it did not feel like much of a deal. The behavior I thought to be malicious later turned out to be just a simple mistake.
Later found out that Abraham Lincoln had a habit of writing angry letters that he never sent which helped him control his temper.
