Wouldn't your husband find it odd to show up for work tomorrow and his co-worker of 2 years was gone. Poof. No sign of him, no goodbye, no explanation?
It would drive me bonkers to not know where they went! Even just knowing that they left would be nice!!
I tell families before a child starts. I am still new so haven't had any children leave but I have a child on vacation this week and felt the need to tell families because she is a missing person when they arrive in the morning and go at night. If I don't mention she's on vacation it leaves them wondering if she was pulled from care.
