A rainy, chilly day means a big book and a hot cup of tea.
The heat from the tea warms your body from the inside out, chasing away any chill in the air. The scent from the tea relaxes and eases your mind, sometimes making things clearer. For me, it is Orange Spice.
The steady sound of heavy rain outside and rushing water in the ditch provides the perfect background sound while you are transported to another world or time by a good book. Right now I am reading the Lunar Chronicles by Marissa Meyer.
What else do you do on a chilly and rainy day?
