I'm gonna go with a 5 until I start talking and it drops swiftly to 0 because if I think I've intimidated someone I will make STEPS to put people at ease.
Mostly the 5 is due to me wanting to go along with the flow of other people and finding out that they were waiting for ME to make the first move and oops miscommunication
I also know that I tend to use longer and harder words purely by accident in everyday conversation and then realizing, oh, a small child I'm talking to probably doesn't know what this word means and backtracking
