Heads Up: Giveaway is at the bottom of this post. If you're feeling all TL;DR about it then scroll away!
My family is a family who has passes on an astounding gift through the generations: that of always being right. This often comes with other genetic traits such as blue eyes, nearsightedness, sweating the small stuff, never letting it go, and having the last word in the conversation.
It's fine and dandy if only one person an average family inherits these genes because the other family members can learn to roll it off their backs with a sigh and intimate reminders to each other that "It's just how he is."
However, when every single member of the family is assured by The Universe that his or her opinion (read: authority) is not only the logical one but also, unquestionably, the most right one as decided by said Universe it can only lead to debate. One that often accumulates in wondering how this person could possibly be related to you when they are so utterly wrong. Probably about everything ever.
All this goes without ever realizing that the other person is thinking the exact same thing.
Oh, the family resemblance is more than skin deep.
As such, I've developed unique methods of arguing with each family member. Though methods might not be the best word...
Tactics. Yes. Tactics is appropriate...
