Thanks everyone for your suggestions. And now an update. My friend just got fired from teaching summer school. She let her students teach her Spanish and guess what they had her say and was videotaped on the student's phone? "Shut up you fucking idiots."
When she realized the student recorded her, she tried to delete it but the assistant principal walked in. He reported her. The principal looked at the recording and asked, "Did you know what you said in Spanish?" Apparently, my friend thought she was learning good, proper Spanish from her high school students.
What an idiot.
