They educate you, they direct you

They protect you, they build you

They challenge you than take it away

They dare you to pour your life to them

Than snicker to others

They criticize your mistakes

They delude your mind

They fall in love with you

They inspire you

They "believe" in you

They get you bullied

They show you who you are

They make you question your thoughts

They say "no answer is wrong" than laugh when it doesn't sound right

They psychologically tear you down

They get upset when you prove them wrong

They make you work hard

They make you lazy

They make you or 

They brake you

"They" are teachers
