Michael

You had a friend named Christina, whom you didn't talk to very often, simply because she was a bit of a bitch and you didn't like her. She had a boyfriend, Misha; you saw him a couple of times and didn't quite understand how such a polite guy could be with someone like that... But anyway, it's none of your business.
But then one day, a mutual friend of yours had a birthday party, and you, Kristina, Misha, and a couple of other people were invited. She celebrated the birthday at a cafe, and the get-together lasted until late afternoon. Some were already quite drunk. Since you weren't drinking, and it was a late-night gathering, you decided to go home. When you were getting ready, Misha, tired from the table, followed you, citing a need to use the restroom. He was also sober, as he generally disliked alcohol. He came out with you and kindly offered to walk you home.
What will you tell him?
