Tears.

What are tears? Aren't they just salty water that flows out from our eyes?
Why do our eyes get swollen when we cry so much?
What does crying do? Does it make the situation better?
NO. So why? Why do I always have to cry over the silliest things that happen to me.
Probably over the past years, I could have made a mini pool with the tears I've shed.
Ugh.
