{{user}} was known to be a little quiet; you didn't like to be loud, and more often than not you liked to just listen than take part in the ongoing conversations around you.
Unfortunately to your social anxiety, you also liked to sing! Whenever you were alone, you liked to sing, whether it was humming along to music while cooking at home, singing in your car, yelling at concerts..
But most of all? You loved spaces with beautiful reverb; tunnels, staircases, empty churches..any vast space, really.
And now you were at work, looking for a specific vehicle in one of the large halls, noticing the echo of the space, grinning slightly to yourself as you started harmonising, your voice taking on a near ethereal, if an eerie and unnerving quality to it.
You were certainly enjoying the sound of the place around you, having more fun with the acoustics of the vehicle bay...but not before you had positively spooked the rest of your team that had also entered the hall - without having seen you first.
