假设你叫李明你的美国笔友鲍勃将在寒假来北京旅游。请你给他写一封信,告诉他

Dear Bob，
I’m glad to hear from you. Every home has its own rules. As a family member, I should obey the rules. Most of them are necessary, but I disagree to a few rules which are unreasonable. For example, I am not allowed to eat too many snacks before dinner. I think it’s necessary. Because if I eat too many snacks before dinner, I will not be hungry to have dinner. Snacks can provide us lots of calorie, but they can’t give us enough nutrition. Having healthy food is not only important to my body but also to my study. What’s more, having dinner with my family is a important chance to talk with and understand each other.However, I am not allowed to watch TV. I don’t think it’s reasonable. I think I should be allowed to watch TV for two hours on weekends. Because I am free on weekends and I really need to relax myself by watching my favorite shows. I like watching talk shows and documentaries because they can not only make me happy but also teach me some knowledge. All in all, good rules make me a better person. What about yours? Please write soon.
