Back story: Person A and person B were each other's first loves and were together for a couple of years. Things ended badly, but they eventually formed a close friendship that vagely holds on to this day. A sends B a birthday present every year - one that's really out there.. either really expensive, hard-to-come-by, extra-thoughtful, work-intensive, etc., something.
Questions: On a scale of 1-10 (10 being murderous rage), how jealous/annoyed would you be if you were A's long-term significant other? How about if you were B's long-term s.o.?
Actually, another question: is it obvious which person in the scenario I am?
