I'm not quite sure what Gavin did but I'm pretty sure it had something to do with the destruction of one of Tanner's Lego creations.
Poor Gavie, I found these slips of paper along with about 30 of their counterparts spread out all over the two stories of our home and in the elevator commons outside the condo.
If you look close enough you can see that Tanner drew broken hearts with cracks down the center. Am I a bad parent for secretly laughing at the passion he put into this "Kid for Sal" project or a good parent for having Tanner pick them all up and promising to never try to sell his brother again? (Hmmmm... Unless of course there's a way for Paul & I to get a 60/40 cut... Just kidding Gavie, love you!!!)
