I think being able to distinguish between a human flaw and destructive behaviour is an invaluable skill to have.
For example, I think getting frustrated watching Man United lose yet again or a snarky comment when under pressure is permissible.
Nobody’s perfect, everyone gets stressed.
But upending the table in anger, smashing plates to make a point or creating drama out of nothing is destructive volatile burn everyone in the vicinity kind of behaviour.
If you can identify the difference early, you could save yourself a whole lot of toxic exposure.
