I'm going to attempt to break down some simple rules for staring.
Here goes nothing.
Don't do it.
If you do it, don't stop doing it.
Staring is like going out for sushi. Just get the fuckin' Rainbow roll and the Tuna slices and the Dragon roll and the Sapporo and the Saki and the Edamame and the Miso and the Fried Banana with ice cream and then tip too much. Really do it up right if you're gonna do it.
Staring is also as filling/rewarding as sushi is. Which is not at all. I've stared lots. It's never gotten me anywhere. Every time I eat sushi I get McDonald's on the way home after. Never fails.
