I'm not letting that go!

I will accept the point that if there is a blind person in the lecture hall
then I should be more careful about explicitly naming things.  But if there
isn't, then I'm going to thump the board and say things like "Now take this
<thump> and put it there <thump> and see what happens".  Not only do I think
it good pedagogically but as a mathematician then it's how I think so why
would I want to deprive the students of that insight?
