I like to live by the idea that you should treat others like you have to explain yourself to Mister Rogers. I open doors for the elderly and I'm nice to waitstaff. I like to listen to others and empathize. I'm a fiercely loyal friend and I don't put up with intimidation or pickup-artist negging bullshit.
That said, I'm sarcastic with a more off-kilter sense of humor. Just don't take it too seriously. I certainly don't take myself too seriously.
