We have a friend over right now and he and Lex are building with K’Nex and blocks. Lex says to him, “I’ll do all the thinking and planning and you can find me the pieces. That will save you a little brain energy.” Isn’t he generous?! He decided they should build a digger. His friend asked what a digger was and Lex replies with, “Geez! Don’t you know your construction vehicles?!”

Fortunately the friend decided to keep playing and they are now working together, nicely, on a castle. I keep hearing “Oh yeah, good idea!” from Lex so I think they are cooperating well. :)
