Earn and Burn

Just like normal days I am leaving from school and I saw that my friend also going by that root and that that I want to say something to him because that was the last of class 10 and I didn’t know when and where we meet. But i don’t know how to approach him how to start to talk him but by last day I really need to talk him. Otherwise I did not get any other right moment to talk him because no one there to see us. But i get courage in myself and I started talking to her firstly I started talking her by saying hi and she also say hi but i don’t know how to talk next and what should I need to talk her.
