Actions speak louder than words. Your actions follow your value system. You can only fake for so long what you really feel inside.

This is why the saying goes, if you give someone enough rope, they'll hang themselves.

We try to make excuses for people, they're busy, they just forgot. And maybe a once in a while thing, but if this is their chronic behavior, you are being way too easy on them. You shouldn't have to work so hard to keep someone in your life who doesn't care if they're there or not.
