We visited my sister-in-law's house a few weeks ago, and my kindergartener found himself playing Barbie and Ken because his cousin is older and she gets to decide.
Here is the conversation I overheard coming from the playroom:
My son: "I have two wives."
His cousin: "Yeah, because you cheated on one of them. So really, now you have a wife and a girlfriend."
I wanted to interject and tell them that this scenario probably isn't all it's cracked up to be, but they already had this whole sister wives thing set up in the dollhouse, and really, who was I to judge...
