one way valve remembers that grandma said "Your father is a cup of espresso," then she continued to said, “he can give a strong impression that many people do not like him. But others cannot live without the excited feeling which he brings. He has a lethal attraction that many people have no way let it go.
"Let me guess, grandma, you're hazelnut taste."
“Do you think I am similar with Hazelnut taste? Why do you say that?"
"Because I found your coffee theory was fanatical." I laughed at my grandmother, but I could see she did not think it was funny. "My dear Alisha, here I want to teach you the truth of life, not to make you kidding me."
Are you explaining the truth of life? Is she kidding? "Grandmother, you cannot take a cup of coffee to analyze a person's personality, in fact, people are much more complicated than coffee. Everyone is different, different personality, different in every aspect. You cannot go around, and then said: 'She is a cup of deep roasted coffee, he is a cup of instant coffee, or he is a cup of mocha almond coffee ...' "
Grandma looked at me with a nearly dazed and frustrated expression in her eyes. "You don’t understand coffee at all," she snapped, then clearing my plate and coffee cup from the table. "I think so," I sighed and was annoyed at my "hazelnut-taste" grandmother.
