So it isn't just us.

My DD is full of catch phrases and has been this way for as far back as I can remember. When it comes to the humor she is quick to say how funny she is and also to tell us that we are either teasing her or she is teasing us. It is usually in line with "I'm just teasing you Mommy."
Catch phrases aside I wonder if DD's sentence structures are normal. She has always had complex sentences but the sentences are getting more and more complex. We visited a friend this summer and DD was horrified by the unclean car and refused to climb in because of it and made no attempt at hiding this information from my friend. It was pretty funny since my friend had been apologizing for the unkempt car and house so the look of horror on her face each time my DD brought it up was priceless. Anyway, her daughter came back with us to stay for a few weeks and DD went to get out of my car and made a point to say: "See, I can get out of your car just fine Mommy because it isn't dirty UNLIKE Emily's mommy's car which is really dirty." Do any of you see this with the 2 to 3 year olds? Basically is this seen as normal speech?
