Dear Grandpa,

may be you forgot that in this board we read a lot of compalints concerning Frank Zhang. What about your memory?

You are (an) English teacher? Plainly spoken, you are one of the agents of Zhang.
It is too revealing that you complain about what others have said - admittedly in quite a rude manner. But you forget to mention the lies and insults that come from Zhang and his gang.

Get some medicine, grandpa, to fight your Alzheimer!
