I recv'd this e-mail:

How did you teach your children what to do when you have unexpected visitors?  When I stopped by your house unexpectedly, there wasn't chaos.  In fact, things were rather orderly.  What did you do?  Do you give bread to every unexpected visitor?

Any time I want to work with the children on something I use non-conflict training time.  This is a time of day when everyone is alert, not hungry and well rested.  I tell the children what we are going to be working on and we do so.  I continue with the non-conflict training until they understand it and can be held accountable for this new item.  For pop-in visitors the general rule is, we greet them at the door (each child says hello and how are you today -- or something along those lines)  Then each child gets a book and sits down to read.  For non-readers, they sit and look at the book.  This allows me time to evaluate how long this visit will last.  Some pop-in visitors are only there for a few moments while other visits can take longer.  If the visit is going to take longer, then after 15 minutes or so, I will instruct the children on what to do.  This is our general rule we follow when we have pop-in visitors.  Of course, there are exceptions to this rule.  If the pop-in arrives and we are in the middle of an activity that the children can continue on without me, then they greet the guest and go back to the activity. 

The bread -- this part of the question cracked me up.  Our goal is to always have an extra loaf of bread available to be given away.  This does not always happen but it is our goal.  We enjoy blessing others (even if it is just a loaf of bread)   There have been days when a company delivers a package and if bread has been baking they will comment on the smell.  I love having a loaf available to give them.
