1:54:31ivereadthesequel Q: Super off-topic, but as someone who is older and perhaps a lot more experienced than someone like me who is younger: do you have anything to say regarding interpersonal issues? Ever encounter people giving you issues, being rude? Even absolute bullies? Do you have any advice for that if one encounters that even as an adult in university or at their job?
