Why do I do this?

To vent. My opinion. Anyone who knows me knows my opinion is the only opinion I care about, and am interested in, anyway.
Basically, my opinion is a box of Honey Bunches of Oats, and anyone else's opinion is the trial offer for a spa that I glance at, then throw away. Meanwhile, I am pouring the Honey Bunches of Oats into a bowl, throwing some milk in there, and savoring every bite. The milk is my own self esteem, which my opinion floats high on.
You think I'm kidding?
