You might think you know how to relax, but he could probably teach you a thing or two.
The only way to really relax is that after you have stolen bites of mom's unguarded tuna sandwich, you climb up onto your own chair that has been spread with a sheepskin rug for your own personal convenience. Then you angle yourself in the sun, roll onto your back, and nap like a champ for three hours.
Then wake-up and demand more tuna.
Make sure to make it clear that you are very irritated when you don't get what you want.
