These days,something unusual is happening in my neighborhood.Mr.Chu often hears footsteps in the hallway at late night.His wife thinks it might be the neighbors.Lao Zheng,a retired worker,saw someone trying to get in the window one evening.Later,he found it might be the wind.Xiao Ning,a Junior 2 student,often finds garbage in front of her house.Her mother thinks it might be cats.But she doesn't think so.My neighborhood used to be quiet.But now everyone is worried.I don't know what to do.
