A kick in the teeth

Why is it that you can distance yourself from your emotions and make a decision because it’s what you *know* is right, and it’s what morally you know you should do – and people will still kick you in the teeth for it?

I’d be better able to deal with this if I wasn’t in an apartment with two people, two cats, a fishtank, and two computers… and no air conditioning.  I’m going to bed.
