小朋友，看得细致！

i fetched my students back today.
arrived her home; after she close the car's door, she knocked me through the window, and pointed inside my car.
i kept looking the area that she pointed. nothing wrong.
but she kept pointing, n i still dono what was wrong.
until she finally gave up.
i watched her going inside her house. then i checked for the last time.
"Oh..." it's my car's bin's lid. They like to play with the lid, and she forgot to close it today:)
