Ahh - I recall once suspecting someone was otherwise occupied on every Wednesday - which seemed . . . odd. Perhaps a bit odder, we were together A LOT on Tuesdays/Thursdays - other days, hit or miss - but Wednesdays, she was always "busy" and not responsive in any way. I found out b/c she told me AFTER this guy had ended things with her (and she told me when we were together on a Wednesday) - my suspicions were confirmed, though unpleasant, I'm glad I found out - and moved on.
