We had a rare and wonderful afternoon at home yesterday. And since the kids all missed the friends they haven't seen much in recent weeks because of their travels, I allowed each one to invite a friend over. Counterintuitive as it might seem, six children are much easier to manage than three, provided that only three of them are your own kids. ;) So, for most of the afternoon, my house was occupied by two third grade girls, two fourth grade boys and two seventh grade boys.
The third grade girls played together with dolls and dress-up clothes and art supplies.
The fourth grade boys played together with DSs. They were synced to the same game, and the two boys were playing in the same game world on separate devices while sitting next to each other on the family room sofa, and also talking to each other about the game.
The seventh grade boys were both sitting on the guest room bed, but not interacting much at all...each on their own devices and in their own little worlds, with the odd few sentences of chatter thrown in.
All three kids had a great time, even though their experiences were vastly different. And if the progression holds, by high school my kids will be having their interactions with their friends purely via the Internet with no physical proximity or conversation needed at all!!
