More Grammar Snobs

I found a couple of the Grammar Snob chapters to be useful this time. I was really glad to see she included "affect" vs. "effect." I still remember asking my 11th grade English teacher what the difference was, and she couldn't tell me. All she said was "effect" is more common, so in most cases it's right. I am glad I actually have the rules now. I also like having descriptions about posessives. I never feel like I fully understand possessives, but I don't know why. Some of the other chapters were boring, but there was useful information in most of them. I felt very creeped out by her "steamy" chapter. Did she have to describe herself taking a bath? Was that really necessary? That's what I came away with from the chapter, and not so much what she talked about.
I wanted to respond a little to our tutor exercise. I do want to restate that I would never make someone read that said they wanted me to read. This just seems courteous to me, and I know in their situation I would be uncomfortable enough anyway. Also, doing the tutoring session and having others criticize my tutoring has made me really self conscious. I notice every time I make a suggestion, and question whether or not I'm aloud to make that suggestion. I think it's ridiculous, and so far we've only been informed by an idealistic book. You can't wait forever for some students to think of a word... I've tried. They become exasperated and beat themselves up for not thinking of it. This isn't all students, many will just go "yeah!" My question to this idea: have you never had a time you knew the word you wanted, but just couldn't think of it? Maybe you'd think of it in a day or so, but not immediately. I think some things we learn are good to put into effect, but I will never purposefully try to make someone feel more uncomfortable.
