I think I am unaccustomed to the enjoying the expression of emotion.
For example, it is unusual for me to express myself through shouting and chanting during sports matches, nor to experience joy while doing it. I don’t think I’m used to feeling anger when I shout either, possibly because I don’t shout when I’m angry, or being angry does not cause me to shout.
Another example: I remember, I had to shout while cheering for school during sports matches, despite not particularly enjoying what I was shouting for.
Similarly I seem to have little practise it seems in enjoying the shared expressions of emotion: I’m not used to singing along with people to a song, I don’t find any enjoyment other than the inconsistency I hear.
It’s interesting. I imagine it can leant and conditioned such that these types of expressions can be closely associated with emotions such as joy, particular through practise such as social events etc.
