Cooking, a difficult task!

Three guests visited us today.They traveled a long distance.In China,a gorgeous meal is essencial in entertaining guests.Eating in the restaurant or at home was op to them.Finally they choosed the later,that was to say I had to prepair for an excellent dinner by myself.

I am not a good cooker,neither is my mother.We racked our brains,however still had no idea what to cook.We cooked our special dishes,tomato cooked with egg,chicken stewed with potato and mixed carrot,which were far less enough.At last we booked some dishes in the restautrant.

However they told us that they enjoyed the meal very much,I knew it was kind of comforting me.Now I deeply understand what an important role cooking plays in wemen's life.It is so difficult a task!It needs not only more practices but aslo the gifts.Maybe I am doomed to be a bad cooker.That is hereditary!
