So I was driving Leah home this evening and was asking her about her day.

What did you do today Leah?
I played.
What did you play with?
I don't know
You don't know?! Wow ! Did you play with Aria today?
(sadly) yes....she's Tony's friend now...but she's my friend too
Well that's good. Are you Tony's friend too?
Yes
Did you play with so and so?
No she said I couldn't play with her or so and so or so and so
Did they let Aria play with them?
No
Did that hurt your feelings?
Yes, they made me sad.

I've known for a while that Leah was growing up way to fast but I never realized clicks start in preschool.
