Tears are salty water secreted by glands  in a person's eye.

Tears fall down on our cheeks when we cry.

I cried when I was once lost at the park, I was young and I felt lonely in a big world.

I cried when I was hurt.

I cried when I broke my leg.

I cried when I fell in love and it was a one sided love.

I cried when my Grandpa passed away. When someone close to you, leaves unnoticed. Life wouldn't be the same again without them. It takes time to adapt to the new situation, but life goes on.

I cried when people around me betrayed me. A world of hatred and deceive where people care for their desires.

I cried when I watched a sad movie.

I cried when children abandon their parents. Parents take care of their children, they never get bored of our silly questions, on the other hand, when we grow up, we become really frustrated and impatient when they ask us something. We should never forget the time they spend while raising us. How much they love us, whatever we do we can't repay them.

I cried when there was too much pressure. I worked all the time and at end of the day, my boss considered I was doing nothing. It was too much, I was fed up. I quit my job after insulting the big guy. He wasn't expecting it. He tried to make me come back to work but I refused. He should know not everything revolve around him. So I guess I gave him a lesson.

I cried when I was happy.

I cried when I saw the person I'd been waiting for a long time.

I cried at my brother's lame jokes.

I cried when my friend forced me to eat hot chilly.

Tears are important, they help us express our feelings and emotions. 
It is a way to relief ourselves from tension and pressure.

Crying doesn't show weakness, it shows that you have a heart and feelings. You have the right to express yourselves freely without any judgement.

So express yourself, it is alright to cry from time to time and let all the pressure fly away from your back.
