The annoying things that most my friends do is maybe they're drunk because they can't beat their own drinking capacity and keep drinking. I've never done that but because I've experienced friends case like that many times. Especially when I was in university, I saw a lot of such friends, and I think it was me who took care of them until the end every time I did that. Because I lived in a dormitory and I rarely drank because I didn't like alcohol. Whenever that happened, I took a taxi to send my drunk friends after the event or returned to the dorm together. I also called their family, boyfriend or girlfriend and told them to pick them up. The next day, I told my friends in a strong tone not to do it agian.
