Miss O told us tonight that she accidentally called her teacher "Mama" today. That always cracks me up. Mr. Z has done that a shitload. He called his 3rd grade teacher "Dad" once, called his 4th grade teacher "Grandma," which I'm sure she fucking loved, and, this year, he called his 5th grade teacher "Dad." He said his teacher looked at him and said, "Dad?! I'm not your dad!"
I laughed at that response at first and then I thought about it for a second. "Wait a minute -- is his teacher saying 'I'm not your dad' like 'You think I look like that hairy freak that loiters in the fucking lobby after school?!'" If so, then them's fightin' words, sir!
But I guess I'd be flattered, as a teacher, if a student called me "Dad." I guess it means the kid trusts and looks up to you like a parent. Or it could mean that their real parent is such a fuck-up that they call any adult who pays even the slightest bit of attention to them "Dad." It's a fine line.
Personally, I don't care who they call what -- as long as they don't start calling me by the janitor's name.
