While Autumn is my favorite season, June is my favorite month. Even though half of it is lost to the school year, that pivot point in the middle of June is part of its charm. June means the freedom of the summer starting before the tedium of too much unstructured freedom sets in. Winter and spring are spent looking eagerly to June.
The weather gives the promise of solid warm sunny days ahead, but not so many or so hot that bitching about the heat is the first thing people say to each other.
In June, July and August are still ahead and you can think "Two months of awesome freedom ahead! What can I DO in this incipient bounty of self-determined time and leisure?"
The days are longest. People look their best. We collectivly brim with optimism. The world is brightest in June.
