She has been friends with Guest for 16 years and his girlfriend for 8 years, so they treat each other like best friends. They are extremely comfortable with one another and deeply in love. Since they live together, they are always together. They occasionally use mild profanity with each other and absolutely refuse to use cutesy pet names like "honey" or "darling."
