Oh Crap!

I'm sort of a man with a few words. I like to say things direct to the point, without any crap. That is the problem with me sometimes. I have these bunch of ideas in my head that I want to write about but I have a hard time making a good and long composition because I'm always afraid I might be redundant or have cliches. If a friend asks for an advice, I'd say what I feel straight away without any crap even (or maybe, especially) when she's wrong and then I hurt her feelings. When I am upset, I burst into madness right there and then without thinking if I have the right to be mad at all. I think I should learn the art of talking crap sometimes... even though I hate craps? What do you think?
