I try to provide significant challenge to students at all levels. So I ask extra work of students who learn things faster. I do have high expectations. Students who don't do the home work, don't do the lab, come late to seminar and so forth are in trouble with me. I expect student to be there and be prepared, so in that sense I am a strict sort of teacher.
Parents serve many roles.
And I do get pretty attached to students and want to help guide them. I see my role extending beyond the material I am teaching. I don't mean by this that I see my primary job as an adviser, the content is really important, but that both the content at student's development are important to me. Building community is a part of what I try to do in my programs. I do things like potluck lunch in many of my programs.
