I know I need to manage my emotions and subsequent actions / behaviour better. I try, I really do bite my tongue but even holding it in I've just got one of those easy to read faces. Even when I'm trying to look nonplussed, people can obviously tell ( my manager commented about it just recently). However, I was just instantly triggered today and if I don't learn new techniques I'm never going to be one of those leaders that I aspire to be.
Today, a member of the team who I've had issues with answers the office phone and was quite abrupt with them. Another member of the team asked who it was after he finished the call and he replied 'just some tart from EDF'. It instantly got my heckles up and I said 'when I thought I couldn't dislike you any more than I do, you call women tarts you repulsive old cunt'. I then went a bit further with a character assassination. In my head and in my heart this is what I felt and IWBU, but I really want to know how others maintain a breezy, professional demeanour. I think eventually my tongue will be my downfall.
Please don't suggest I should apologise to him though, he's going in 2 weeks and his feelings aren't that important to me as he has the self awareness of a stick (which I also mentioned) so it would make no difference.
How do people manage their thoughts not manifesting into words and actions? This isn't necessary about the context of this example so I'm not looking for flaming or congratulations, just techniques if you have them.
