Zach vs Legos

Zach was building with his Legos yesterday. He was trying to make the tallest tower/ robot (they look the same to me, but apparently there are major differences that I cannot see) that he could. Three straight times, he built a decent tower-bot only to have it topple over. After the third crash, he just sat there and looked completely defeated. That's when I captured the first image. Then, after thinking about it his situation, he decided it was fun when they toppled over and started building them just to watch them fall.
