What are you two supposed to be doing right now?

Oh, the girls. It's funny how they follow under my feet all day, asking me play or if they can have a snack or watch TV or play play-dough... but as soon as I tell them to clean their room, POOF! They are gone and I don't hear from them for hours. Of course, their room is 100 times messier than when they first went in there, but they are playing so good together! I tried to join in their play today, here's how the conversation went:

Mom: So who are you guys?
Adi: I'm the mom
Piper: And you're Ella Enchanted too!
Adi: No, just the mom right now
Piper: Oh.
Adi: Remember?
Piper: I'm the mermaid, but not the mermaid that swims, the one that sings
Adi: No you're the daughter
Piper: No!!!!!!!!!!!!!!! (followed by unintelligable screaming)
Adi: Fine, you be who you want!
Piper: Fine, I will!
Adi: The cow is Papa and the bunny is Nana
Mom: So who am I?
Piper: You can be Aunt Whitney (my own baby sis)
Mom: Ewww... I don't want to be her, I'll be a princess
Piper: No, Aunt Whitney is pretty and nice and smells good
Mom: Ok, if I have to be. What should you guys be doing right now?
***cloud of dust as they run back into their room and slam their door***

Oh, the joys of motherhood!
