>>>You should be a role model for me to follow.
...I am, as long as you do what I say...when I correct a mistake and make a comment, it is because I expect you to know better
>>>put it bluntly, the more I put into it, the more I get out of it.
...yes, yes, when you have studied for 20, 30 years - come back to me and tell me what you have

>>>leave a lot to be desired=leave much to be desired=leave a great deal to be desired
...I know what it mans, I wanted you to show ME - where we could improve...and why you think so.
