I know exactly what you mean!
My social studies teacher was talking about how strict she was about iPods in class, but allowed cell phones, as long as people weren't texting. She said another teacher gave her the idea, and told us which teacher it was. I decided to tell her that he changed the rule so said "He actually changed the rule you know, he allows kids to text in class now". I was in his class the last semester and he DID change the rule, but she translated to "I loved to text in his class, can you please let us text?" and responded "OK, whatever, but I am not going to allow you to text in class". When she said "you", she was talking directly to me.
