I'm going to be in my brother's room alone with his girlfriend
How do you think your brother will react to you being alone with his girlfriend?
I don't care what he thinks. I like her and want to be with her.
You may not try anything with your brother's girlfriend, but knowing that you like her, being alone with her is a bad idea. Stay out of your brother's room and find your own girlfriend.
What the fuck? I really thought we could come to an agreement.
Would you be okay if your brother spent time alone in your room with your girlfriend? Don't you think that you should respect your brother's relationship so that he also respects yours in the future?
