I have office hours every Monday, Wednesday, and Friday, from 1:30–2:20. (My office is in 3070 Wescoe Hall.) You are also entirely welcome to make an appointment to meet with me at another time. (Indeed that is often preferable to dropping by during my office hours, since I may already be talking with someone else.)
To make an appointment to talk to me, please send me an e-mail with a list of some times when you are available, as follows:
I am a student in your Introduction to Ethics class, and I would like to find a time to meet with you to discuss some questions I have. I am available tomorrow after 11:30, on Wednesday between 12:30 and 2:30, and on Friday after 12:30.
Sincerely,
__________
Then I will be able to select a time and write back and we will be all set.
