Pre-teen eyes

I look at the world through whole different eyes now that I have a pre-teen male in the house. We took a trip to our neighborhood branch of the Houston Public Library last week, which isn't how you expect an adventure to start out, but that's how our life goes. After finding my books I went to look for C-boy, or Radical Dude as he calls himself these days, in the Manga section. I walked past the handful of "hobos" (the kids favorite word) trying to escape the record heat and humidity and bask in the AC. I turned the corner and was greeted by half of this girls back showing and half of her buttocks. This is after she pulled her pants up and her shirt down.

She looked up and saw Collin and me so, she sat up and we walked around her. I was glad to get on the other side of her, only to be greeted by this/these:

The only reason Collin didn't notice too much was because she wasn't blond. He's got it bad for blonds. He thinks they are H.O.T. I can sort of handle that, it's to be expected from boys and he's got a lot of Bybee genes in him. But then we went to the grocery store and I heard him start laughing like a 5 year old and yelling at me to come see this:

He laughed and snickered over it the rest of the afternoon. Repeating it over and over. So what is worse? Oogling over cleavage, or regressing into a 5 year old??? I waffle . . .
