What exactly counts as meaningful interaction?

According to my understanding it is not necessary for it to have an universal definition.

What I mean is that, meaningful interaction is situation specific, should be seen within the concrete context it is happening in. Cause every interaction inherently starts with certain dispositions, certain expectations and it follows an impromptu interaction order, as Goffman and some symbolic interactionist would say.

People invest at the least some effort into interaction cause they have an idea of the returns they would be getting back, however small. Returns could be in form emotional support, information or just simply companionship.
