Trust me, she was happy to see the photo of S & D, but she's not going to say anything to you about it. Just let it go and go on about your business. However, she may mention it later on when you least expect it.
Well, you certainly have given her ample notice about when you are going to be off. She can't have her cake and it too. She's got ample time to reschedule things and besides, she can take the children to see their grandparents. I'm sure they would love to see the kids. She'll get over her snit.

Keep up the good work!
