An elderly lady was telling me about the time she was in class in the late 1940s. She was with a group of girls, all wanting to become teachers, and speaking with each other in Chamorro.
In walks the teacher, herself Chamorro, who says,
"Ha? Todos hamyo para en fan maestra ya ni sikiera ti en tingo' man fino' Englis?"
"What? All of you are going to be teachers and you don't even know how to speak English?"
"Mampos butlona," the lady told me.
"She was such a tease."
