Dear Dr. Green, My relationship with my mother is worse and worse now. It seems she's never tired of talking. She talks here and there,day and night. More seriously, I feel like we don't have much common. She doesn't always understand what I'm trying to say. What should I do?Yours,Jim | Dear Jim, I know how you feel. It's not easy being your age. And it 's not easy being a mother, either.It's common for kids to have trouble talking with parents, and talkative mothers are not new to teenagers.But remember, she's nagging (叨唠) you because she just wants what's best for you. Talking is her way to show love and care. And she also wants to know more about you.After a day 's work. she's tired, too. But she will never be tired of caring about you. Kids should learn to understand and care about parents.In my opinion, it's helpful to share school life with her. Then, you talk and she listens. Doing some housework together with her is another good way for you two to know each other better. And if possible, often tell her your feelings about the things around you. Always keep in mind: be polite and patient.Yours,Dr.Green |
