I can understand you

I hate it when people just assume that you don't understand anything, and they don't even give you a chance. Many times I've been walking with some people, and someone will ask a question about me, but since they thing I wouldn't understand, they ask my friends, or host mom, or whoever. Usually when that happens I answer the questions, to catch them off guard and let them know that I actually do understand. For example: the other day I was in the car on the way to school with my friend and her little brother. The brother asked Alba (my friend) when I'm going back to England (the brother and dad think I'm British). She was like I don't know, ask Chloe. This has happened many times, and it makes mad.
