First bad tantrum

After ballet, we hung out at Barnes for a little while me and mommy finished our studying. The week prior, we promised to buy you a book if you finished your jobs at school and behaved like a good kid--and you did. So we told you to pick a book but you picked two instead. We told you to either pick one or you don't go home with a book at all. You decided to throw a tantrum instead :-/ It was a tantrum unlike anything I've seen before. Mommy got really upset. I was a little disappointed but I hope it taught an important lesson in delayed gratification.
