Dear Dushant,
I have this very clear memory of little me sitting in front of God for days and nights asking for only one thing - "Please give me a little brother", I don't clearly remember why I asked so, maybe I didn't have anyone to play with. And you were born. So, technically your birth is an answer to my prayers and thus you are HIS gift to me.
I know sometimes I completely ignore you, don't give you much time and go with a dry conversation. It's all my mood. And I go on doing this because I know you'll understand me and you do!
We are more of friends and share almost everything but I choose to behave responsibly when I am around you because I can see many things from childhood you have directly adopted from me and it's my responsibility as an elder sibling to make sure whatever you get from me is the best.
I'll be always standing by your side no matter what.
If you do something good, I'll be applauding you and if you do something wrong, I'll be the first one to slap you. Hope you remember that slap :P
My advice for you would be - Don't change, your version of living life is awesome. Be a strong person, don't ever give up!
You are more closer to our parents than I am and it's a good relief for me. I am very sure you are going to have an AWESOME life :)
