Are there any choices you've made in the game that you regret? Like events that you've accepted or purchases you probably shouldn't have made?

I'm asking for therapeutic reasons seeing as I just "sold" my brat Blue Ivy to the talent scout for 500 coins. I instantly felt remorseful since she was 12 and would have outgrown her brattiness soon. But she was just a little monster. I couldn't turn around without her banging dishes or tearing books or writing on the wall and just basically disrupting her parents from their work constantly. No amount of punishing or reinforcing positive behavior did the trick and in a moment of frustration I sent her packing like the evil person I am...but again, not without now feeling bad for doing so. I guess it could be worse. I could have sent her to boarding school or something. At least now maybe she'll be famous.

So anyone else have similar experiences or regrets?
