The WAS is human and despite being seemingly full of resolve and a full steam ahead attitude is in some cases suspectible to second thoughts and the implanting of new ideas.
In the classic WAS/LBS dynamic, the LBS gets caught up in "not reacting" or not wanting to seem as if they are noticing the WAS. What would you have done if you saw FloDad wearing those shoes in normal circumstances? Maybe said something like "Nice shoes!" and winked or laughed? I don't think that there is anything wrong with a few selective instances of "normal" behavior or interaction. It shows that you are still on even keel and capable of a fun, light, playful moment. The LBS tends to forget "fun" and can become very "dour". True for all of us!!!
