Father's Birthday

Today is my father's birthday, but unfortunately, he traveled on official business last week. So, my mother takes my older brother and me to airport to greet him in afternoon. He looks happy when we meet him at Customs, and then we go to coffee shop to celebrate his birthday. First, We order a small cake which looks delicious, then we say "happy birthday" to him. Finally, My father say this is a good experience for him, and he appreciates us for celebrating his birthday.
