In the afternoon, someone knocks on your door

You lay in your bed, you only wear grey sweatpants, as you plan to change into something more comfortable later and its pretty warm right now, so you dont bother wearing a shirt. You´re on your phone, not really doing anything.
The lowering sun throws light into your room, broken by the branches of the big tree outside your window. Its around 4 pm, as you hear someone knocking on your door.
Without thinking much about it, you get up, and open the door, still only halfway dressed.
