Just because it’s short or brief DOESN’T mean its “token”. Just because a conversation goes for 5mins, doesn’t mean it’s “token”.
Token describes an assumed attitude. You might be making it “token” by the fact you don’t really care. It’s your attitude that’s token – and that shows in your action.
But if you do think something is valuable, worthwhile, important, etc. it doesn’t matter how much time you give to it; either brief or long.
Something can be important and at the same time, brief. And all without being “token”.
