Google software engineer Shivani Singh's postcard moment looks a little like this:
“It's 12 p.m. The intersection of Green and South Wright streets is bustling with activity — students running between classes, squirrels hopping in snow, and cold winds gusting through Green Street.
"All of a sudden, the majestic bell tower next to the Alma Mater commences its noontime chime — 'Joyful Joyful We Adore Thee' — and orchestrates chaos into music.
"I have crossed this intersection several times, and even today I can replay this scene before my eyes.”
