When you are a person working full time / business hours, you are VIOLENTLY PROTECTIVE of your free time. What’s more, when someone asks you do something during work hours, your first response is I CAN’T DO THAT, I HAVE TO GO TO WORK, AND WHY DON’T YOU JUST GO DIE. Second Response: Uh, so, sorry about that time I just yelled at you as if you were infringing upon my civil liberties. Thank you so much for the invitation, how kind, but unfortunately, I am otherwise engaged at that time.
