You are right. I try to be a woman of my word. It is hurtful to say yes then not follow through. But it also hurts people too when they have a problem saying no, and they yes, and always follow through because those people usually don't get the same consideration from others and always get the short end of the stick. That is why it is always best to say no when you really mean no because letting someone down when after saying yes sucks; on the other hand, yes people who do follow through can get bitter when things aren't reciprocated and that sucks too.
