["One of my friends wanted me to leave out my other good friend and not tell her about our beach trip we were planning. I told her that I wouldn't go unless we could all go together because I just don't leave people out.", "That's terrible. I'm glad you stood up for your friend.", "I am fiercely loyal to my friends and don't think anyone should be excluded, especially among a group of friends that are all going but one person.  Not cool."]
Why would your friend want to exclude your other friend? Definitely not cool.
