Brotherly Love & Bumblebee

Peter is playing with Bumblebee.  Lachlan says nicely "Peter I want Bumblebee, he is special to me."  Peter takes a few more steps as the words Lachlan spoke sunk in.  Then he stopped in his tracks turned around and brought it back to Lachlan as he sits in Jeff's orange chair.  Peter turns and walks back to the little table to play.  As I say "Ah, that's so nice that he gave Bumblebee to you, you should . . . "  as I was about to say you should say thank you Lachlan was hopping down off his chair and putting his arms outstretched saying "I want to thank him."  Peter was unaware until I told him that Lachlan wanted to give him a hug.  He turned around and ran into his brothers arms where they remained in a lovely brotherly hug for quite some time.  I don't remember the details of what followed but it was ended with a statement about being best friends, a hand shake and an invitation by Lachlan for Peter to join him on the chair.
