So funny.....and so true. I found it hilarious that you guys eavesdropped and I think you got found out - hence the "he's a great dad" code. Pretty funny having to stop the car - I know how that laughing goes! lol.
I try to have "code" phrases and words, but my dear husband always ruins it by saying "What, what?" And of course everyone stops talking and looks at me so I can't repeat the code or say anything except maybe "inside joke"....lol It's at those times I want to kick someone leg under the table, but with my luck he'd say "What did you kick me for"???
Maybe the kick is your code.
I've developed the "hell eyes" look and it works sometimes.... :)
