Ok so Ruby reminds me of two of my classmates at uni who would CONSTANTLY go to the office hours. Every time we started new semester with a new teacher they would keep coming to their office hours so the teacher "remembers them". Often it would annoy other people so much, because f.ex. we had to come to the office hours to take an exam if we were absent and so on and these people would come in and talk for so long about total bullshit while everyone else was waiting by the door for like an hour. At some point they became so desperate with one of the professors (they wanted an internship at his legal office or sth) that they would sit by his office door for HOURS and come in for "talks". I swear it was the cringiest thing at uni, I still get embarrassed for them even thinking about it. I bet Ruby does the same thing and doesn't get a clue that maybe other people actually HAVE to go to the office hours and she's wasting everyone's time by coming in to try to "get to know the professors".
Sorry for a double post but she's such a grandma (not only from her behaviour but also looks), chill out a bit ffs.
