The same guy keeps coming to my office outside of office hours. Always when I’m busy (but generally doing something like writing). We even discussed in class why it is important to come during office hours and not outside of office hours. (Note: lest you think I’m a horrible selfish person, this is a BIG required core course. If I let everyone who has just one quick question interrupt me, I would never get tenure. There is a reason I have office hours, and generous ones. There’s also a TA for the course they could ask.)
Update: I was teaching my seminar class with the door open (it gets stuffy and claustrophobic without) and the same kid stuck his head in the door and asked if I could help him with his homework from a class I don’t even teach! During a class discussion that this kid was not in. Luckily his friend was there and said something to the effect of, “Dude, that’s a class. She’s in the middle of teaching.” After my class was over he caught me again, and boy did I chew him out. His friend (also in my class) helped. I told him in no uncertain terms that I did not want to see him anywhere near 2pm on Tuesday (his favorite time) this coming week. (Wed, Thurs, Friday all have office hours and the TA does too.)
What do you do when someone trespasses on your time?
