(scenario) Your best friend is in a car accident and you two got into a fight an hour before. What do you do?
I don't even have to think about this.
I would immediately go and try to find my friend. I would do my best to help them, even if I had to fight off the firefighters and police or whatever. An argument is no reason to not do something nice for you friend, no matter how bad it was. If you are friends, you are friend, and you WILL help them. That's just how it is. You don't have to be petty about things.
I would do just about anything for all of my friends. Maybe I'm just weird, but I love them all.
