Your boys will have no clue what it is -- just that some man gave their dad some papers. I would just smile and say "thanks! Have a wonderful day," hug your kids, and proceed with all the fun plans you have for them for the week.
SD, I'm a firm believer that God doesn't give us more than we can handle. In my sitch, things seemed to come in waves, and I used to wonder why that was. One day I got the revelation that had everything happened to me at once, I wouldn't have been able to endure it, and I think that's true.
All I've seen from you since you started posting here is a very worried "what is she going to do?" personae. I think God just threw you a bone, in that you've been forewarned about what she's going to do.
THANK Him for it, and use the foreknowledge to move on in a confident way. You'll likely have at LEAST 30 days to respond to it, if not more.
How much do you think it would irk your wife, if you responded as per the above? Will your wife be there? Maybe a "have a wonderful day" to the server, with a wink and a smile and a "Nice -- classy" to your wife, as you sweep your son up in your arms with a hearty laugh??
