I'm at uni and I've a teacher (hb8, Korean, Ph.D student) for a class in my major that's giving me notable IOI's. The first day of class she repeated my name often, I caught her staring directly at me at least three times, and after class I told her her english (which she was self-conscious about) was "pretty good" and she very very sheepishly
thanked me. She asked us to send her pictures so she could remember us, so I tested the waters by emailing her a picture of me pulling back my eyes (like miley cyrus) and teasing her and she replied with a smiley face.
How do I go about this? Nothing I've read tells you how to go about gaming a professor.
