Smart people don't have to say "Hey, I'm really smart." Badasses don't have to say "Look, I'm a badass." Rich people don't have to flash big wads of cash. The list goes on and on. If you're something, you don't have to say it.
So, when someone makes a claim on the internet, my first reaction is "Uh, no. You are not."
BTW, I'M AN ASTRONAUT AND A COWBOY!!!!!!
