So I went to my 7-year-old's room this morning to give him a quick goodbye hug/kiss on the head before he left for school and on my way out I bent down to say "good morning" to his goldfish and from behind me I hear in a voice that I can only assume is my son's impression of his fish if they actually had voices say "Oh, hi Grandpa!" followed immediately by my wife's burst of laughter from the other room.
Grandpa?! Um, no, fish. I am not your grandpa.
And grandma in the other room better pipe down.
