Where is the trash?

Xiao Ming's mother always put the trash in front of the door.But these days，the trash disappeared without any trace.Who takes it away？Here are some inferences.

At first，she thought it could be some animals taking it away.But there are not footsteps around the house and she didn't hear strange noises at night.So she guesses it can't be animals.Then what is could be？Could it be the cleaner？However，why the cleaner didn't take away the trash in front of her next­door neighbor's house at the same time？So it can't be the cleaner.Might it be aliens？They are interested in the earth.They are also interested in people's trash.But people are still not sure whether there is such thing.She also thought it might  Xiao Ming or Xiao Ming's dad.But they are too lazy to help around at home.Then，who might do it except them?

The next day，she especially gets up early to solve the mystery.To her surprise，she sees Xiao Ming putting the trash into the dustbin.She realizes her boy has really grown up.
