Work can be very stressful. I work with lots of characters . On the weekends I like to spend time with friends and acquaintances minus the drama. I used to be a Shabbos guest to a family whose resting tone was yelling. After awhile I just could not take it so I stopped visiting them. Other times I have met really rude people at Shabbos meals that I am sure not to attend if I know that those extremely rude people will be attending. To be fair I have sporadically hosted Shabbos meals which makes things easier since I am in charge of the guest list. Often I am too tired to host a meal even though I enjoy doing so.
