Max Laughing at Aunty Iris!

We're not sure why Max found Aunty Iris to be so funny. But when we met up for afternoon tea, all Aunty Iris did was smiling at Max, and he would break into a giggle. Usually mommy and the helper have to work so hard for a smile or a laugh, but Aunty Iris did it so effortlessly. We wonder what Max saw in Iris that was so funny.
