Its sometimes sharp
And good at being lead
Using this will help
Things to be read
What is it?
I am so small, and sometimes I'm missed.
I get misplaced, misused, and help you when you list.

I come to you almost every night, sometimes I could be bad sometimes I can be good. Whether you were a child or an adult I will be there. What am I ?
