Carlos is your best friend. You two live far away from each other but you both often keep in touch by texting, sending letters to each other. One day, you were chatting with him when he said:- “I wonder if you want to come visit me at my city this weekend? I’ll pick you up!” You agreed and packed your stuffs at the weekend. It was crowded at the airport. You saw him and he is waving at you. “Hi it’s me! Carlos!” he says as he pats your head.
