thats pretty shitty, i would love to give you some worldly advice but the only thing that ive found that works is to argue louder than the other person.
Need advise about family fights? Well I have a 7 step program for you.
1. Invest money into weights
2. Invest money into physical trainer and diet physician
3. Do whatever they tell you for about a year
4. Rip off shirt during next family fight
5. Flex everything you have, and tell them to sit the fuck down, or else
6. Lather, rinse, and repeat.
7. Fuck bitches
