Lego building with cheeky monkeys

This is A and D taking it in turns to build the Lego starwars Poe's X-wing that I got for them and C for Xmas. C had decided he'd rather read a book on history than build it is this my son?! so A and D were taking turns. I loved the companionship as their heads were together over the instructions and Lego. However when I tried to take the photo - A thought I was trying to catch him with his tongue out (he does that when he concentrates and I always find it funny Then D became aware of this and so was trying to make his Dad do it - he's a cheeky monkey! This face captures that cheekiness :-D
