"Raid" To Go Home (although this is not my story, it is really touched)

My mother said that my home is a hotel, I am a passenger, and she and her father are waiters. She is responsible for taking care of me as a passer-by.
At ordinary times, when I study abroad, my studies are busy and I have a lot of affairs. It often takes a long time to go home. My mother always told me that whenever I go home, I must tell her in advance. I asked why, and my mother smiled and did not answer. I had to do what my mother said. So every time I go home, my mother always takes my heavy burden at the railway station and uses my own car to take me home. I entered the door to greet me with a full table of delicious food-dad's cooking is really amazing, and his dishes are mouth-watering.
On one occasion, the school offered a vacation in advance. This is because the school decided to take a holiday in advance, so I had no time to inform my mother, and I went home directly. Just a taxi, and my footsteps are faster! Now that I am close, I can finally see what my family looks like. The ancients cloud "near home", and I am "near home", I really do not know what kind of surprise this "raid" will bring to Mom and Dad.
Finally, I opened the house with a trembling hand: "Dad, Mom, I'm back !" My mom and dad were eating dinner and saw me entering the house. They looked so happy and surprised that they had to put the chopsticks to help me get the bag.
"Yan, why don't you tell me in advance today ?" "I did not come and said !"
"Yan, it's a hard job to study. You see, you have lost a whole lap. Don't bother yourself at school. You have money to eat, you know ?"
"You know, every time you come back, you say this, it's a bad thing ." I'm a little impatient.
"I'm so arrogant, well, I don't want to talk about it. Eat ." Mom smiled and said, "I am going to wash my hands. Oh, Mom, what's the food today ?" I casually glanced at the dinner table. Oh, my God! There are only two bowls of radish soup and a dish of pickles on the table.
"Mom, do you eat this every day ?" I think something is wrong.
"No, no. Today, your father said that he had to eat too much food to lose weight. I am doing this ." Dad also hurriedly said "yes ". But his eyes showed a strange look. I got stuck, and a bit of bitterness poured into my mind. The three are speechless.
"Why are you still waiting for a face? Come and have a bowl to hold the meal !" First, my mother broke the silence. I went to the kitchen. "Ah ?" I was shocked. the leftovers in the kitchen were white, except for the cabbage, such as tofu and soy sauce. These are incomparable to the big fish and meat I eat every time I come back. My heart is tight. My mother lied to me just now! These are what they usually eat. I can hold back the tears in my eyes and hold the rice bowl silently. This rice bowl is like a kilo ......
It is the nest of love forged by poor parents with meager strength.
