In life, You'll realize that there is a purpose for everybody you meet. Some are there to test you. Some will use you. Some will teach you. And some will bring out the best in you.
Life is, in a lot of ways, just like a party.
You invite lots of people. Some will leave early, some stay up all night, some laugh at you, some laugh with you and some show up really late.
At the end, once the fun is over, some of them will stay to help you clean up the mess, even though they never made it, and it is those people who are the ones who truly matter, the ones you know you can count on.
These are your true friends.
