Joan and Natty were two young mothers who lived across the street from each other.From their living room windows，each woman was able to      the activities of the other woman’s family.

One day，Joan said that she’d been watching what    in Natty’s front garden and that she envied her.“I don’t know what you     ，” Natty said with a     look on her face.

“Well，I often see your husband out in the front garden mowing the lawn(修剪草坪)，and I      my husband would do the     thing，” Joan said.“Your garden is beautiful！”

Natty      and then made her confession(坦白)．“I have been doing the same thing，Joan，” she said.“I watch your     in your front garden—and I have        you！” Joan shook her head with disbelief.“What       do you mean？” she asked.

Natty replied，“I see your husband playing ball with your son so     .How I wish Keith，my husband，would do the same thing！He       wants our boys in the     when he mows.Be honest，Joan.Would you rather have your husband        with your son than have a beautiful lawn？”

“I had not        that before，Natty.       you’re right Natty.I may have tall grass，but Eric，my husband，is         about playing with little Johnny，” Joan concluded.
