THEIR teacher.  Maybe you need to spend more time LEARNING than making stupid remarks. 

You are not the only one who called their teacher a boomer. *wink, wink*

I am a boomer, so, most of my teachers were pre-boomers.  Many were veterans of WWII.

It's 'their', not there. Maybe you should listen to your teacher instead of being a dummy.

Your teacher evidently didn't do a very good job.
