LoL nice one
But still i don't agree 100% to it. There is many options.
For example you really want to learn something from teacher then listen to him. But there is many of them who's asking for brick and a kick for their attitude to students. In that case of course iDad's advice fits perfectly.
In other case you can litlle rephrase that "sticking...
If you where good students and listen carefully and used lessons which teachers gaved then just say that your job look perfect from the point of skills level which you (teacher) gaved (or so - my eglish is at level - "i speak english a little"). You get a point.
And i assume you pay for that lesson so....
Or be more philosophy and say that after spending a night in watching your image and hours of meditacion you understud that "perfection doesn't have representation" ... say "ommmm" turn around and go away
(or hit his head with stick and then say "ommmm" - even better
P.S. After all phrase about that picture could be improved are true ... because "perfection doesn't have representation".
P.P.S. Sorry i know it will not help much but it's about 2am here and my brain is "dead".
