Dude teaches girlfriend's 12-year-old trash-talking younger brother a lesson in video games: 'His friends were now laughing at him and he was on the verge of tears'

It's generally accepted that you should let kids win at things there's nothing more embarrassing than watching a grown adult demolish kids in sports or games. (The iconic "Billy Madison" scene of Adam Sandler playing dodgeball with kids comes to mind.) Of course, there are exceptions to this rule—like if you're an uncle—and there's more of a grey area around how long this should go on.

When they get a bit older and into their teen years, depending on the relationship, you get a free pass to whip them into shape and teach them another life lesson: that nothing in life comes easy. 

A lot of us have probably mistakenly assumed that our superiority, experience, and skill will allow us to continue to win things uncontested… That is until your younger brother is suddenly bigger and stronger than you, and now you can't relentlessly pick on him or take him in a fight—and find that it's actually probably the other way around…
