I sure do. Idiot neighbors, coworkers, people in public especially niggers... I have a very, very hard time smiling and masking my utter hatred for all of them in even the simplest interactions. I can see the awareness on other people's faces. They might dismiss me as rude or an asshole, but it goes much deeper than that. When I do try to smile and be polite, it probably comes across as insincere which is why I don't really try anymore.
Every interaction is just a transaction. Why try to sugarcoat it? I don't need to know how is your day or exchange shallow pleasantries.
