What We Are In For?

My daughter posted this on FaceBook today after spending a couple of hours at the pool with her kids (so she says):

They all arrive on Tuesday for a week's visit.

My husband is the pool chaperone, so I guess that, if this is in fact a true account of today's activities, dealing with this supposed behavior will be his fate.

But I am shocked, SHOCKED, I tell you.  I can't believe that this is a true account of what went on today.  

OUR grandchildren would never behave like this.

My daughter is slandering her own children!!!  Shame, shame.
