Look at Flash Sentry. Hitting on Twilight and being all nice to her. How dare he? He sucks.
I'm Shining Armor, and as Twilight's older brother, I'm the one who has to approve of whoever dates her. Or whoever wants to date her. Or, in the case of Flash Sentry, might even think about wanting to date her. But I don't like him. Not one bit. I have a visceral hatred of him from the very core of my being. So, I kick Flash Sentry's flank.
He deserves it, after all, and I'm sure that you all agree.
