You know you're the mother of a boy

Today I took Max to the library on our "date."  V. was sick, so we decided to have a little evening out to ourselves instead of going over there.  I wound up reading him a little book called

The Bridge Is Up!  It's a cute little book; pretty repetitive.  The bridge is up so the bus can't get through and has to wait...a car comes...the bridge is up so the bus can't get through and the car can't get through, they both have to wait...and so on.  Max liked looking at all the different vehicles and saying the line, "They have to wait," with me.  Then we get to the page with the bulldozer and I'm reading it to him and then I hear myself say, absentmindedly, "That doesn't look much like a bulldozer, does it?  That's a front loader."  

Then I realize what I'm saying and that I actually now know the difference between a bulldozer and a front loader and am able to mentally chastise the illustrator for sloppiness here.  

Can you tell I've been bombarded with cars and vehicles in the form of toys, books, pictures, etc.?  I guess that comes with the territory when you have a little boy.
