Not sure whether to put this in this thread or the terrified thread. I figure here because I handled the situation like an emotionless cyborg.
So I am a 16 year old boy in his last year of highschool. I was waiting around my maths room for the teacher to arrive, and was talking to friends and things like that. Apparently he arrived and I didn't notice, along with a bunch of other people. So we keep milling around waiting, the this maths teacher from the opposite side of the hall (a good 15 metres) swings open his door and starts yelling something to the effect of,
"This isn't a social area! Get into your room!"
I was kind of taken aback by this, and as he continued his angry tirade people started to shuffle towards the door, but I didn't. Not out of any active rebellion, just that I was still watching to see what he'd do. He then notices me paying attention to him and gets angry at me personally (even though he was still speaking. Really it would have been more rude to leave while he was still shouting.) and asks, "Are you in that room‽" to which I reply, "Yes," because it was true. But instead of leaving it at that he says, "Well go on then, why aren't you in there?"
And then, and I shit you not, he sticks his arms out like he's trying to make himself look bigger, starts striding over to me with hugely exaggerated strides and torso movements and yells, "Or do you want to make something of it?"
Right here I start internally flipping out internally because I thought I would seriously have to beat down this almost-bald, ginger, middle aged maths teacher. But he stops about 15 cm from my face and starts flipping out in my face, keeping a horrifyingly intent level of eye contact the entire time. Asks me if I said, "What" to him just now, and I told him I'm pretty sure I didn't. Then he gets angrier and I remain outwardly perfectly cool and just answered his stupid questions as calmly as possible, for example, why I was outside the room and not going in (which as I said earlier wasn't exclusively me), and why I was looking at him, he asked if he, "Wasn't loud enough." I said that it was actually the opposite and that I was looking because he was being incredibly loud and it was kind of startling. He gave a sarcastic "Right," and then I echoed "Right" (but in a less dickish tone) because saying the same shit other people say usually shows that you're agreeing with them. Instead he took this as great a great offence and stayed silent for about 15 second then takes on a tone with enough venom in it to kill an elephant and asks "What did you just say?" I then had to spend another 30 seconds or so explaining how it is that I was trying to agree with him (diplomatic lie, he was actually chatting absolute shit but whatever gets me away from the unstable angry man the fastest), then he finally left, saying something like "Look, now you've kept [teacher] waiting. Get in there now!"
Sorry sir, but it was in fact you who kept me out here for a good 3 minutes.
And the entire time I managed to keep a straight face. Though I couldn't really do much useful with my hands for the next 10 minutes, keeping from showing being nervous is hard.
I wouldn't blame you for thinking I'm exaggerating and being a resentful teenager or whatever, but I'm not. This is actually how it played out. Mostly the aggressive stride and an intrusion way into the proximity where I stop feeling comfortable talking to somebody are the things that pushed this into terrifying thread territory though. The rest of it after that was just a bit surreal. People aren't meant to act like that, especially people who are given a position of authority.
