I couldn’t understand her.“She shouldn’t be feeling sorry for Tiffany!”I thought.“She should be feeling sorry for me.”

One day,I couldn’t help saying to Morn,”Poor Tiffany?Lucky Tiffany! She gets everything she wants! Why do you feel sorry for her?”I burst into tears.

My mom sat down next to me and said softly , “Yes,I do feel sorry for her.I have been teaching you a lesson that she will never be taught.”

I looked up at her.“What are you talking about?”

Mom said with care,“One day she will really want something.Maybe she’11 find out that she can’t have it.Her mother won’t always be around to give her money,and what’s more,money can’t buy everything.”

She continued,“I have taught you valuable lessons by not giving you everything you want.You’11 know how to look for bargains and save money,but she won’t.You’11 under stand that you need to work hard to get the things that you want but she won’t.When Tiffany is a grown woman,she’11 wake up one day and she will be wishing that she had a mom like the one you’ve got.Life lessons are more important than modern clothes and delicious food.’’
