We stole a kid yesterday and hit up the zoo and McDonald's.
That's basically it. Except that 3-year olds are pretty much the funniest things to happen to this planet and they say the best things. Like telling you that there are two kinds of pumpkins: happy ones and sad ones. Or they whisper "Hey. Heeeeeyyyyy. Ben. Heeeeyyyyy." before succumbing to roaring like a lion to get your attention. Or they start dancing around excitedly anytime you pass water (a lake, waterfall, drinking fountain, etc.).
Oh, to be 3-years old.
