[blparent] language use concern

[Jodie and Kahlan]

We have a neighbor who throws  F bombs frequently in regular 
conversation, and today he used one with Kahlan. Kahlan hasn't 
indicated that she's going to start using it, or even that she heard or 
understood it. Should Chris and I talk to her about it, or just leave 
it alone unless she actually starts using it? Chris didn't hear it 
because he'd gone to the store to pick something up for me. I asked the 
neighbor not to use it and he did apologize, but he's done it 
frequently in normal conversations where she and all the other kids can 
hear, including his own, and his kids can be pretty disrespectfrul. 
Should we bring it up with Kahlan, or leave it alone? Chris and I have 
already decided she's not allowed to play at their house anymore.
