I always go for D asap which ends up being C. I don’t want to have a superficial conversation with someone I may never see again. For some reason I am more commonly asked “Any plans for the weekend?” and I always just say “nope” which usually ends the conversation there. One time someone hit me with a “Any plans for the holiday?” which really threw me off because I didn’t have a canned response and I said “I’m picnicking” and I just felt so awkward and embarrassed that I froze and felt like covering my face.
