The green dinosaur

My parents are in town for my son's 3rd birthday and the baby's Baptism.  They are sleeping in the baby's room, since he is still in the bassinet in our room.  My mom snores something terrible, and it woke my 3 year old up, he started crying, and my husband went in to see what was wrong.  While dad was trying to comfort him, my mom got up to use the bathroom.  My son heard her shut the bathroom door, and he said "Oh good, the green dinosaur finally left."  All day we've been teasing her about being the "green dinosaur," and my son keeps growling and telling us how the green dinsaur sounded in the middle of the night.  What imaginations they have at this age!!
