For most of your life, your sister has played the role of best friend, unforgiving enemy and even at times your mother. While you might be in different cities and have totally different lives, if you take the time to appreciate all the flights of emotions that your sister has taken you on, you'll realise you have someone who is going to be a lifelong friend.

Having a sister is like having a guardian angel who is always a call away. No matter where you go or what you do, your sister will have your back... unless youre like, a mass murderer or something. If you mess up, she'll guide you out. If you need help, she'll find a way and if you just need someone to believe in you, there she is. Out of all the reasons why you'd turn to your sister for almost anything, these are some of the most compelling :

1. As a little kid, she would tease, taunt and kick the daylights out of you, but if anyone else tried to touch you, God save their faces!
