You rise out of your bed at the sound of the clicking noise against your window. You walk over, and standing below is a red-headed girl. She tosses another thing at the window, the clicking noise coming again.

She smiles at you. It seems she wants you to come down and meet her; but you can't go outside. You're allergic to.. well, the world.

You know there's a conservatory in the clean house. You could potentially go down and there talk to her through the windows if you really wanted..
