This Thursday?

Okay, I'm sure I'm not the only one who has ever done this, but it is disconcerting, nonetheless. I have "10:00 am" written on my calendar for Thursday, Aug 18th, and nothing else, no identifying info.

Please forgive me if this is a brunch date with you (and do not take it personally), but I truly have no idea what I'm supposed to be doing at 10:00 am on that Thursday! If we have plans, will you please call or email me and let me know?
