This is said - usually - after they have been given several worksheets of problems that they have not worked. Suddenly I am supposed to create 5 or so problems out of thin air that are appropriate and easy to work.
Then explain to me why they get offended when I say find one of the worksheets you have been given and we will work the problems out.
I am not saying I will not help them. I am saying that, with all of the problems I have already given you, I don't want to have to make up more just because you 1) don't want to open your notebook 2) didn't bring your notebook or 3) don't want to go over to the table to pick up a worksheet.
