It's not quite random. Every time I fly on a one way ticket, I get tagged for special screening. I plan for it.
As for the eyebrows, I don't understand the "shave them off and paint them back on" thing. My goal is to have eyebrows that put Edward Teller to shame. It bothers children.
I do without trying, in fact when I cut my hair I trim my eyebrows. I've actually had them bother me while skating, they droop down too far...
Now, convince me why I want to let my eyebrows run amok. It can't be just to bother children. Even with my trimming habit I had family members a few years back comment "you inherited your father's eyebrows."
Oh, I agree, when I see a woman with painted on eyebrows I wonder what they are thinking, it looks so strange.
