rude teachers

So for art we are designing t-shirts and I showed mine to my teacher. He asked me "Would you were THAT?" Like it was the worst thing he ever saw!  Said "yeah I have a shirt like that and I were it all the time." He gave me a look like I was crazy and walked away. I thought the school motto was to treat people like you want to be treated if I treated him like that he would give me a detention! grrr so unfair and so rude!~Too School For Cool
