If you you see your bros family in need of help you help them.
If an asshole hurt your bros sister/niece give them a....chat yeah a chat.
If your bro thought you how to drive using their car fill their car up with gas.
If you have food/drink pass it around so that your bros can have a bite/sip.
If your bro and his girlfriend had a fight, be the one to help them make up.
Something better. Like if a bro says he slept with a famous movie star, don't say you slept with a Victoria Secret's model (let a bro have his moment).
