How do you feel about me not defending my friend?
Why don't you want to defend your friend?
He couldn't defend himself, so why should I?
It could be hurtful not to stand up for your friend. You should always try to be there for them.
If he couldn't defend himself against his mother, then he doesn't deserve my help.
You need to stand up for your friends, especially when they need you. How would you feel if he didn't stand up for you when you needed someone?
