He loves trains! He loves letters! He loves his name! What could be better than trains that are letters and that spell his name? Actually, I know what would be better. If the surfaces of the letters were mirrors, Aizay could look at himself and he loves looking at his own image! In fact, if we let him look at pictures or videos of himself and then we take them away, he abjectly cries, "Aidaay! Aidaaay! Aidaaaay!"
