9. Confidence is your middle name.
Say it. Repeat it. Keep saying it until you start believing it. No matter what, if you think you’re not at fault and can win the argument in question – go all guns blazin’. You need to be absolutely confident to be taken seriously. Be careful your show of confidence doesn’t come across as over-confidence or ego. Your ego counts for nothing in front of hers, know that. Also, be very sure that you’re not coming across as a condescending prick because if you do, may the lord help you. The conversation will then digress and unfortunately for you, only for the worse.
10. Thumb rule
Don’t laugh. Never ever laugh. Not a giggle, not a chuckle, not even a smirk because then she will be fucking livid! Because no matter what you do or say, there is no comeback to,” do you find this funny?”
All the best, comrade!
