I see myself as a crayon, I may not be your favorite color: But I know someday, you will need me to complete your picture!
You deserve the world jaan. But unfortunately I can’t give you that. What I can do is give you the next best thing. My world.
When you look at me: My heart melts; My eyes twinkle; And my face lightens up!
Some people have nice eyes… some people have nice smile, others have nice faces, but you have all of them with a nice heart!
If you want me in your life, put me there. I should not be fighting for a spot.
Do you know that your smile takes 1000 people to death? Save the world… so please start teeth brushing regularly
