I have a friend who is fluent in French, Spanish, and English, but she didn’t want to learn a new language during high school so she took French and pretended she didn’t know it. Long story short, her first year didn’t count because the principal found out so he made her take Spanish and when I walked her to Spanish on the first day, she walked in and said, “Hoe-La uh-me-goats!” And personally I believe she might pull this off
Update: after two weeks of pulling it off, the teacher asked her to read something in Spanish and she forgot that she was supposed to sound inexperienced, so she read the whole thing in perfect Spanish. Her counselor is now considering transferring her to German
