The one who’s unreliable
That friend who’s always canceling on people arrives very late, is overall very irresponsible, and is definitely not someone you would want to have around you for a long time.
Someone you can never rely on couldn’t care less about you or your efforts, which makes you wonder if this friend has enough respect for you.
Unreliable people will never think twice before canceling on you last minute, for something else that’s more interesting to them.
This type of attitude will slowly kill your self-esteem, which will make you feel as if you’re not worth the trouble.
