My Confusion Over Butt Cracks

I'm not confused by butt cracks themselves, but rather how a person can go for an extended and very public period of time not knowing their butt crack is showing. I've seen more cracks in the last couple of days than I care to count. How can you not know your crack is showing? Does that sudden breeze on a part of your body that is normally covered not alert you to the fact that it is out there for everyone to see? Do you want people to see it? I think that's the only excuse. You must want people to see it. And that's weird. So stop. Wear an extra shirt, hike up your shorts - spare the rest of us from becoming more familiar with you than we care to. Please and thank you.
