Wandering Along the Path: Right Speech

I'm in a bind.  There is only a week and a half this summer that we have plans to go away, and that week has been when everyone wants to do something with us.  I thought I'd explained it all to all my kids, but now I'm going to be losing and opportunity to see my granddaughter.  You'd think something could be worked out, but the kids have their plans and they definitely clash with this trip we're taking.  I've got to let go of magically somehow making things work out.  This is beyond my superpowers!  I've been perhaps over responsible in the past, and I find it torture to say no to my kids, but slowly I'm learning that I can't orchestrate this family any more.  They are way grown, and I'm no longer in charge of anything.  But the familiar guilt hits me anyway, reasonable or not.  Same old, same old.
