University instructor likes me or am i imagining this?

you should mention your uneasiness to your personal tutor or head of studies. One of the younger tutors asked me out for lunch once as a date (creepy i know..) and one of the married ones actually winked at me last week. these guys are guys after all. they are human. they have desire. they arent going to hold back just because they are unleashing their knowledge to you. keep it in mind!
