Sorry, Lwb. I guess what I wrote wasn't very clear. The weekend in reference was this one just past.
My W worked this past weekend -- all day on Saturday, but she had just a couple of patients scheduled for the early morning hours on Sunday (yesterday). Her original plan was to proceed directly from her last patient Sunday morning to the beach-front resort community where the "Nursing seminar" was (supposedly) to be held. She and the OM would have had most of Sunday afternoon for fun in the sun followed by a romantic evening together. The seminar was supposed to have been this morning, Monday, (assuming that was not a complete lie) and I'm sure she would have driven back late this evening after spending as much time with OM as possible. Their plans changed when she apparently came down with a head cold.
W had asked me to clear my schedule to be able to keep my S's an extra evening, and then be able to drop them off this morning for the bus (for S6) and with my MIL (for S2). This also meant that my appointment with my IC (who had been our would-be MC) Sunday evening had to also be postponed. I had agreed initially because I enjoy getting as much time with my S's as possible. I then discovered that W was not going alone.
