Today, I was talking to my friend in Spanish because he understands it better than English. We were in the middle of a discussion about a TV show when some guy from our school ran up, spat on my shoes and screamed, "I SPEAK SPANISH, STOP TALKING ABOUT ME!" and ran away. FML
Knock knock! Who's there? You're a dumbass. I'm OP and he already knew English pretty well, he just doesn't excel in it. Let's also just keep in mind I live in Texas and we were only having a casual conversation. The purpose wasn't to help him understand the English language, it was just to have a normal conversation. I don't think continuing conversations in his first language will make him automatically forget his second.
