Yesterday the 21st was some dedicated to ended Conflict and such like so we've sort of missed the boat on that one perhaps.

A thing they've done in previous years at least is to encourage people to Make Peace with someone they were previously on bad terms with.

Humans have a lot of common in things with each other regardless of whether they don't yet like peas, e.g. they all breathe and eat while they live and they share a lot of the same problems. Most of them for example think Wanye Zest is a douche even they like his music: I think if individuals are able to appreciate those aspects they share in common (where applicable and positive to overall improvement of everybody) and appreciate their differences in an opposite but similar way) this would be the Good Thing.
