A Teenager Already?

I was taking a shower this morning and I heard a little bit of yelling coming from across the house. Some mornings Wes puts up a little fight getting dressed quickly and some mornings Chris doesn't have patience for it, it seemed like one of those mornings. I got out of the shower asked what all the yelling was about. Chris said, "Mommy, what do you think of Wes's outfit?". "It looks very handsome", I replied. Wes looked at me, rolled his eyes and said, under his breath "Ugh, I knew she'd say that", then walked away in a huff. What the heck? Did I walk out of the shower into a time warp and it is suddenly 10 years later? I thought Wes was 3, not 13!
