When I picked Tyler up from daycare today, Kathy told me "Tyler is the most polite non-compliant child I've ever had!"   Apparently when she asked him to clean up his toys, he told her "No tank you!".

He does that with me, too when I try to get him to do something he doesn't want to do.  "No tank you! No tank you!"  As in, "Tyler, it's time for a bath", he'll respond "no tank you!"  Yeah, he's saying no, but it's so freakin' cute it's almost hard to scold him...
