I have been singled out by a teacher which has caused me to have a lack of education in a subject which some teachers call mandatory to attend, and have been sent out for ridiculous reasons. For example I was sent out of a lesson for saying the word 'what?' to something the teacher said, and as apose to dealing to this in an adult manner she impersonated my voice in a babyish voice saying that 'it's common manners'. I asked her why she's impersonating my voice and as a result sent me out, without any work or guidelines for the lesson to take into isolation, causing me to fall short of my colleagues in th work. In other lessons she would send me out of her lessons, sometimes for fair enough reasons, but would leave me out of the lesson for sometimes as long as 30 minutes, leaving a student out of the lesson with no supervision. She then would say to the SSO's things that were either untrue or over exaggerated to make me seem worse and to make it seem that I was being unreasonable. The recent incident that I found the most unreasonable to my education and reputation is when she was talking about homework and I spontaneously yawned for no reason to cause offence or to disrupt the lesson, but the teacher said 'Jack it's common manners to put a hand over your mouth'. As she said this I said 'sorry I yawned' and she decided that despite my apology and despite the fact that it caused no disruption to any student sent me out of the class and had me sent to isolation. Just as the SSO turnt up she over exaggerated my yawn and described it as 'a humongous yawn' and also as 'inappropriate behaviour'.
