What does “old school” mean to a kindergartener?

My six-year old granddaughter was recently telling me about a teacher who periodically subs in her kindergarten classroom. The sub is a retired teacher and, apparently, is strong in classroom management skills.  Lyla told me that when the boys in class act up, the teacher puts them in “time out.”  I asked Lyla if she had ever been put in time out and she told me “No.  She only puts the boys in time out. She’s old school.”

“Only the boys?” I inquired, thoughts of Title IX swirling in my head.  “Yes,” Lyla replied.  “Only the boys.”

“What does she do if a girl misbehaves?” I asked.

“She just tells the girls not to do that again.”

“Hmmm.  So she treats the boys different than the girls!”  I observed.

“Yes, Poppy,” Lyla declared with some exasperation.  “Like I told you, SHE’S OLD SCHOOL!!”

DAWG BONE: I THINK I WILL LET THAT GO WITHOUT FURTHER COMMENT.
