Legos and imaginary friends

Oh, the Legos, we've gotten a lot of mileage out of these over the years.  Rielee informed me that I need to buy some girl Legos now because she loves them. 
I heard Ava and Harper talking today and Ava said "after we play this, let's play Googy Gaga. I asked what that was and they said Googy is their "pretend" friend.  She was in the play room and they brought her out to meet me, she is 4 yrs. old, too.  It was so cute how serious they were about her, she ate lunch with us and they both were talking to her, and for her.  Then another friend showed up, but they couldn't think of a name for her so they called her Gaga, too.   She had a baby named Rose.  Made for an interesting day, to say the least!
