Play cards
I feel comfortable with my life in a stately mansion.
The stately mansion proves how rich my owner is, but I do not know how he earns money.
He often wears a high-quality suit, and sometimes wears a military uniform. He wears a sweat suit, and do weight training in a gym in the stately mansion. He has the gym in our home!
He looks like a body builder or something, which makes me wonder how old he is.
One day, I found a deck of cards on table of my owner.
It is also called Trump in Japan.
My owner likes to play with Trump as you know.
Anyway, I bet a card game is familiar to mathematician, because a quiz of probability is often about probability based on card game, in addition to a dice and a coin.
The cards have four suits, and each suit has 13 cards.
It is just a simple card game.
I started play card, in this case I can do pyramid and solitaire.
Whereas, these two games are enough for me to relax myself.
