Let me start by indicating some logical flaws in the timing of the events: The office hours for the class were from 12.30 to 1.30, Monday and Wednesday. The class was starting at 2pm. According to your account, I showed up at 1pm, being 30 mins "late". Then the first student came in at 1pm and came out at 1.20pm? Then it took me another 50 minutes while I was running around? So I came to talk to you at 2.10pm, when I…
First off, many of the details you cited are inaccurate. However, its pointless to argue over such things. I was not aware of your health condition, but given the pattern of treatment given to me and a handful of others, I was left to assume you were acting as usual. Anyway, my post was to make you aware of a few other reasons as to why you received a low evaluation score. Blaming the students wholly is unjust and th…
Perhaps much of the "pattern of treatment" that you observed could be equally explained? When we interact with someone in a bad mood, we tend to assume it's because of us, but it's often likely to be external factors. Having taught before, and held office hours, I can tell you how absolutely exhausting it can be. Maintaining a fair demeanor gets increasingly more difficult.
Also consider how a professor feels when meeting students outside of office hours, and the student has not made a prior appointment. How would you feel if the professor showed up at your home and said they had to hold lecture now? It's obviously not the same thing, but it may give you an indication of how it feels.
