You did the right thing by confirming and saving yourself. Why would a person make plans and never show up or call? What kind of relationship do you have with this person? Did you misunderstand that you had plans?

I'm sorry I said these were 'crappy' people and was judgmental (as Bill pointed out). People who don't show up because of anxiety are not crappy people, I didn't mean you guys. It's my friend who I know does it to pull some sort of self-driven power play and it really irks me.
