If a friend stood me up for no particular reason and made to attempt to explain their behavior, then I would downgrade my interest accordingly.
If a friend had the tickets for the concert (expensive outing) and made me miss some or all of the concert? they had better have their keg in a cast next time we see each other and a refund for my ticket.
There's rudeness, then there is a consistent passive hostility. I don't need friends to abuse me.
