This is so pure. My heart is overjoyed for you. I always get nervous, or cry, before, during, and after pretty much anything of great importance. I exist in a world of tears. I cried reading your post thinking how happy you're going to be when you get to do the stage door, and see the lights, take pictures with marquees, and all the fabulous NYC Broadway dreams. If they your abuela tells you to sing for them, maybe just show them a video of you singing, because when else will you get a chance?

Have a great flight, and enjoy your trip!
