Women often get upset (for good reason) when they are first called "ma'am" after being called "miss" for a long time.  It's an unwelcome sign of aging.  For me, I'm still taken aback when people call me sir.  But that got me to thinking... what is the male equivalent of "miss"?  What was I called before people started saying "sir" to me?  Hey you?  Bozo?  I can't say I ever recall being called "mister".  I don't look that distinguished yet do I?
