My mom and I am fighting. We used to get up so well .But these days, she has been arguing with me about me not come home. She thinks I should spend more time help her with the housework instead going out a lot. In her eyes, I'm just a lazy boy whom only loves playing. The fact is that some of my friends and I are going to different school soon. so I want to spend as much time as I can with her now. I know I should try to understand the situation from her point of a view. But I hope she can understand what important these friends are to me.
