No, I'm not kidding. No, you are not in some bizarre time warp back to 1984.
Ok, I know, I've been hearing about how the 80s are coming back. Whatever. Go buy some parachute pants or a nice pouf skirt before you even consider this monstrosity. Turn up your collar, roll up your sleeves, do whatever you have to do.
I have to go now. My eyes hurt.
