Like all children approaching the age of 2, Luke enjoys exercising his right to say "no" when asked a question. It's that whole "expressing independence" phase. He doesn't really get too sassy when he replies "no" but it is very matter-of-fact. He has developed two funny habits though related to this...
1. The Denial "No" - This is usually used when the answer is obviously yes, but he's in denial about it. The most common example is related to diaper changes. He thinks he can keep on playing and avoid the diaper change all together if he just looks and acts really busy and ignores the obvious. Usually, this "no" is accompanied by the action of running away as fast as possible.
2. The Fake-Out "No" - This version involves the standard "no" soon followed by a mischievous grin and "yes" as if to say "Ha - I tricked you with my first answer!" This one is utilized when asked if he's tired or sleepy (and then he really is and answers "yes").
