New friend

There is a great big black lab that lives across the street.  Her name is Allie.
The girls LOVE Allie.
A few days ago they went across the street by themselves (with permission) and knocked on the neighbor's door and asked if Allie could play.  They played outside with her for a while then let her into the house (unbeknownst to me) and played with her in the house for a while.
They were thoroughly disappointed when I made them take Allie home.
