I am a male freshman in university, and don't have many friends as my modules are mostly taught in a flipped classroom fashion.
There is a module I'm taking right now and since I have been struggling academically for awhile now, I am always the last of my tutorial group to vacate the venue due to the huge amount of questions I have regarding the material.
There is this particular guy who always comes early but is from the next tutorial group that shares the same tutor. We have met a few times as the seating arrangement in class is pretty much fixed and he is always waiting for me to pack up. He has started a conversation a few times like "How do you find this module?" and I kept making my conversations short, firstly because I should get going in my situation, secondly because I do not really know this guy as a friend or even an acquaintance, thirdly it's because I'm an introvert who often finds continuing usual conversations difficult, much more for awkward ones with strangers. We didn't even exchange names but he always talks as if we know each other. The only commonality we share is perhaps having the same tutor and having the same seat, in different time slots.
In the event of such similar encounters, what would be the appropriate action?
