Perfect day would be either its raining outside, I'm sitting on the couch by the river, my favorite novels all have a mass release, no assignments, projects or homework to worry about and a cup of hot chocolate is in my hand
OR
It's a bright summer day, I'm at the park with a great book in hand, sitting under the shade of a tree, reading the book while watching the people go by and my friends are off playing tag or something. Would be nice to have a slurpee in hand
So basically either by myself in the rain or with friends in the summer
