I like looking out the window in my room.I miss you when we are not together,and I trying to find you and looking forward to your return.My mother.
Since I was born,I have never seen my biological father.Mother would not say anything about him.Whenever thought of my father’s left,I was felt that I would never obtain the love from him.I felt my life is not complete.But my mother has cleaned up all the doubts and worries that stucked in my heart.she gives me all her love.
When I graduated from junior high school,I came to America with my mother.She helped me to find the senior high school,settles down my life.Since then,we can hardly spend time together.I always alone at home.She rarely goes home for dinner.At that time,I often lean on the windowsill and search for her figure.Yet for countless nights,until I’m sleep,she’s still wasn’t home.
One night,my mother was home late.After she’s home,she lies on the sofa.I put a quilt on her so that she won’t caught a cold.Suddenly,I found that there was some blood stain on her shirt,it makes me worry.After a closer look,I saw some peeling on her hand.At that time,I couldn’t hold for me is selfless I burst into tears.My mother had paid much for me.Since I opened my eyes,she always working hard so that I could lead a better life.I feel that.I think I should give her more care.
The windowsill is my favorite place to stay because I could wait for you back home,my mother.I want you to know how much I love you.You gave me life and taught me how to live.Thank you for all the times.You wiped away my tears,calmed all my fears,and help me by my hand.
I’m lucky because I have a selfless mother.To me,she is the person I love the most.For as long as I can remember,she always by my side to give me support,confidence and help.I gradually felt her sincere love for me,and her love for me is beyond compare.I will cherish my learning time so that I can get into a better university and achieve my dream .I want to use my lifetime to repay my mother,the woman who loves me the most in this world.
