I feel our friend needs an apology from our other friend.
Why do you feel your other friend needs an apology?
I feel like we've been mistreated and we deserve an apology
It can be hard to stand up for yourself and others but it is good for you do it. Otherwise people will continue to take advantage of you.
I hope you're right.
I think I am right in the situation. You should always stick up for your friends if you know what you're doing is right.
