Who?

Who will help them when they don't understand?

Who will guide them they are lost?

Who will cheer them up when they are feeling down?

Who will fix them?

I will help them. 

I will guide them. 

I will cheer them up. 

They do not need fixing. 

They need a person who will teach them. 

They need a person who will motivate them. 

I am that person.

They are my students. 

I am their teacher.
