Ok, picture this, the year is 7,000 B.C. Two cavemen sitting around a fire, one looks at the other one and says, "Where did you get that little rock? You're not going to kill anything with that stupid little thing!"
The other caveman looks down and says, "This isn't my killing rock, this is the rock I use to to hit your ol' lady over the head with before I drag her out in the bushes."
9,000 years later and nothing has changed; why you ask?, because we are MEN, and this is what MEN do.
We love to give each other a hard time.
There are many reasons we do this, testosterone, boredom, and from a womans' point of view, stupidity.
All of these reasons are somewhat true, but the real reason we do this is simple, because it's frickin' fun!, end of story.
If someone gives you a hard time and you take it personal, then get pissed off, game over, you lose.
The correct strategy is to retaliate, preferably upping the ante.
Case in point, some guys I work with shoved a small tree under my car, then tied it to my back axle with about 20' of rope.
I get about a half mile down the road, look in the mirror and see a tree following me.
While pulled over cutting loose the tree, they drive by me laughing, giving me the finger.
A week later it was me, driving by them, finger in the air laughing, as they sat on the side of the road cutting giant zipties off of their driveshafts.
So the next time your buddy gives you sh!t about your Blaster, just laugh it off with him and piss in his shampoo bottle before you leave.
