Grrrr

My newest friend is a bit grumpy. He is being silent and moody and I can't figure out why. His usual quirky and playful nature have subdued and he just dazes off into the abyss for hours at a time. I know he may not have an exciting life, or lead extravagant adventures but his sullen behavior is cause for alarm. Perhaps a new hobby? Maybe he needs to look at the bigger picture... Or maybe I should just change the water in his bowl.
