Like in my early 20s I worked in an office environment and made a friend "Anne". Well Anne thought I was funny and enjoyed scooting her office chair over to my desk to get some giggles during the workday. Anne also had financial and anxiety issues and appreciated that I occasionally bought a gram of weed for her. Anne also had marital problems and would vent to me because I was a "good listener". To others, it probably seemed like Anne and I were very close friends. But in reality Anne just enjoyed the benefits she got from our "friendship" and I enjoyed having at least one coworker who wasn't passive-aggressive with me at work. And in the end, Anne tried to sleep with my then-boyfriend, orchestrated herself getting let go so that she could collect unemployment and then never called me again.
