Input: Text: this happened about 30 minutes ago and was the most awkward and embarrassing moment of my life.
bit of backstory first. i'm 17 in sixth form and about to sit my a level exams in a few weeks time. i chose maths as one of my a levels and mechanics as part of the course. 
my mechanics teacher was hopeless. either she didn't know what she was teaching us or she just wouldn't turn up to class and when she did she would always seem distant and hardly pay attention to us at all! it was pathetic! 
so today i had a huge rage about her to my pure maths teacher explaining how vile and putrid it is of her to be so careless about our education and that she should be fired from her job. this went on for a while until i was literally red in the face!! my class was silent and my pure maths teacher just says," you don't know why she hasn't been in?" to which i reply, "because she is pathetic?". he then went onto describe how she is in mental state of depression due to her 18 month old son dying only a few weeks before from breathing problems. i immediately went silent and my entire class turned to look at my in disgrace! 
so yeah! i'm literally hitler!
