Dear Eric:
Linda and I have been best friends since we were six years old. We often study and play together. It’s great! But she often gets unhappy when I get better grades than her –she really gets jealous. Should I keep taking her as my friend?
Yours,
Alice
Hi Alice,
I think friendship is important in our lives. You should talk to your friend. Tell her you’re both studying and it’s common that sometimes you get a better grade and sometimes she does better. Tell her you’re going to compete(比赛) with her and try to beat her in every test . maybe you can tell her that if she beats you, you’ll buy her some chocolate or something like that. If you can make your schoolwork into a game, you’ll both win in the long run (从长远看), and you will both start to get better grades in your subjects. If it’s a game, you’ll both enjoy school a lot more, and you’ll still be best friends.
Your,
Eric
