I sent her a message telling her that I'll be in town for a week at the end of the month, telling her (with a wink) to clean her schedule and cancel all other plans. Here's her answer:
"Good evening! Actually I haven't got many plans for that week so far!

If I'm not wrong, you will also catch [a social gathering with common acquaintances, let's call it X Afternoon]!"
What's a good answer to this? I was thinking of something in the lines of:
"You mean X Morning? I'll definitely show up there, what do you think I'm coming for? Though, they should've chosen a name that also includes poor B-people like myself."
(We're both B-people with irregular day cycles whenever we don't have to go to work)
