Big vs. Little Grandpa

Currently, we are visiting my family in Massachusetts for the week (more pictures and blog entries about the trip to come) and I had to post this before I forgot...My grandfather lives with my parents, and I call him Grandpa. Ryan calls MY Dad Grandpa, so we decided on our last visit, last summer, that he will call my Grandfather "Big Grandpa." Before we came up here, we talked about who we were going to see and I mentioned "Big Grandpa" and Ryan said "And Little Grandpa!" He now refers to my Dad as Little Grandpa...Today at one point neither of them were home and Ryan said "Where are the 2 Grandpas?" He cracks me up!
