My take, as a very blunt person myself - even my friends tell me I'm an asshole at times -
If people can't handle the blunt, non-sugar coated truth, fuck 'em. That's their issue and their inability to deal with reality - either the reality of the situation, or the reality that the actions they are taking are portraying them in that particular light.
None of that is your fault. Some people are too weak to be able to deal with the truth without safety gloves and training wheels. The rest of us are what I like to refer to as 'adults'.
This is my family. It may be little, and broken, but it's still good. Yeah, still good.
