I think it's appropriate to get upset when someone cancels. I think it is more adult to only commit to something you intend to follow through on.

Life happens. Sometimes some people cancel. But if you're one of those people always canceling plans, be prepared to find your invites become less frequent, and people not planning things around what you say.

I've come to the point where if I don't know whether I want to do something I say "I'm not sure yet I'll let you know" and then always actually fess up and let them know one way or another, or say "yes" or "no" and follow through no matter how I feel. And I expect the same of people, people who get to know me who are used to peer pressure find themselves initially worried about saying no, but then I find, pleasantly refreshed when I just say "OK." People that flake a lot though get annoyed with me, because I hold them to what they say and give them a hard time if they don't follow through.
