Let go of the anger. Shake it off now. Why let it ruin the rest of your day?
Let H worry about rude and inconsiderate. His actions, his loss.
Why are you expecting more from him? Why do you let it bother you when he doesn't make the grade? And that he didn't say "sorry". How long will you give him the power to make you angry?
The man has limitations right now. He may or may not change. Accept that for what it is. The sky is blue. You can be angry about that, or indifferent to it.
Don't go out and stay out for spite. Go out because there is somewhere you want to be, and something there you want to do.
