Incorporating multiple scenes from the protagonist's life with a song in the background is a classical movie-making technique, to show friendship, romantic love, or even tragedy. The title song from 'Dil Chahta Hai', where the friends go to Goa tries to represent youthful friendship, 'Sajna aa bhi jaa' from Waise Bhi Hote Hai shows romantic love, and Up! shows a life loved together.
There are countless more of course, and every time I watch one of these, I feel happy for the people on screen, but it also makes me feel empty. My life seems so slow in comparison, without such intense moments, where you make silly faces to see your shadows in the sun or put atta on the love of your life. It seems full of classes, and experiment running, and cooking and eating out at random places, and planning and grocery shopping.
But last week, I sat and visualized the "high points" of my life - times spent laughing with friends, planning surprise parties, traveling together, playing antakshari, and I realized that "my song" was much bigger and more intense and more fun than the stuff I saw on screen - its just that putting the video together takes so much more time. In fact, the New York trips alone made for enough footage for an entire movie - I just wish I could have recorded it and kept it in my memory forever. :)
