you say it as if it's a weakness but why? Rhetorical question, but a valid one.

Mine too! That stuff can cut deeply; don't imagine it washes off me just because I can usually handle it. I've been left literally shaking after someone's had a go at me, and it has added to my long-term mental health problems. It affects my work very negatively - it deteriorates. I remember wanting to punch myself in the face on the train on the way home I was so upset, less than a year ago. It should not happen.
> in spite of my efforts to toughen up
I really do not know if that's something a person can do to themselves. Or should? I don't mind if I fuck up and get it in the neck but if I get it in the neck cos someone's rowed with their BF last night then I shouldn't have to deal with it at all. But that's life I suppose.
Holy shit though people calling the above video bullying have no idea. There's no hint of sadism. There's no hint of using aggression as a persuasive tool. No hint of coercion. He's just irritated and there are visible signs of restraint and attempts to mediate this irritation.
