if you say you'll do something do it.if you don't and the person gets upset because you hurt there feelings again after you said you wouldn't they have every right to be upset.especially after they have had a mental break down because of all the let downs that keep occurring.don't say your going to be there for someone if your not.don't lie and say you will be if you know you can't then just say i can't be here for you.but dont be just another one of the countless people who let me down over and over again.
