This just seems like it would be way too much of a headache unless you were a 4th year and they were a intern. IMO, Med School is one big pile of climbing a mountain, only to need to climb even bigger one when you reach a summit. Personally, it has been very hard to emotionally tolerate the stresses and concerns of students in the classes below me. Step 1 wrecked me and encompassed my entire life for 6 months to a year. Once I was done and was balancing shelves, rotations, step 2, planning 4th year, and getting LORs, it was really difficult for me to put in the energy to help and listen to the woes of those going through what I had just done. That isn't to say I don't sympathize with them, but I just don't really have the ability to adequately engage in those topics once I've surpassed them
If I was a resident and I had a MS1 partner who was stressing out about their Neuro 1 final, idk if I could handle it/take their stress seriously considering the stress I was going through as a resident, especially if that stress was negatively impacting the relationship.
Its akin to trying to date a high school senior when you're a freshmen in college, or dating an undergrad as a grad student. Its exhausting and hard to find common ground to relate it in such different worlds.
If you're trying to just do a FWB things though that's probably pretty dooable lol
