Where am I describing ?

The artificial lights shine down on the rough, dirty carpet.
Pieces of beautiful artwork hang from walls and ceilings.
Posters are carefully read by the people inside.
Different voices can be heard inside this place.
“Hey don’t touch that!”
“Stop that's mine”
“Can you get one for me?”
These are all conversations you would here in this place .
Sounds of heavy footsteps and yells can be heard.
Devices are used.
Hands shoot up like rockets here.
Children swarm to areas of excitement like bees around a hive.
There are tables and chairs set around the place.
Books are read and silence is expected at some times.
An adult starts to count down 10, 9, 8,7
 The sound of chairs squeaking surrounds the place
