It's one of those moments when you're at the right place, in the right time, with the right people, singing the perfect song that reflects your current feelings-- This one rare moment in life which you can never repeat again. And if you happen to do so, it will never be exactly the same. Cherish these moments. Live in it.
Breathe in the smoke, scream on top of you lungs, sing the song like it's your anthem, dance to every beat (or off-beat), raise your hands, and cry if you want to. Be as sensitive as you want, or careless as you'd like. Live in these moments. Trust me, it'll be one of the best time of your life.
