dhanraj swarnakar - LOCK

Lock is not of same size
And it is also the house of some flies
Its key is also different
And it is actually an element.

Lock has many livers
And they don’t shiver
They move without a sound
When the key is turn around

Lock can also rust
But it does not burst
If it is coated with oil or grease
It is protect from then monsoon breeze

Locks are of small, medium
