Last week: travel time, more than an hour, much of it in traffic barely moving.
This week: 20 minutes.
Weather: hot, muggy, terrarium in the sun.
Car's inside temperature: hinges of Hades.
Library's inside temperature: air conditioned.
Conclusion of the matter: It is better to be at school a full two and a half hours before class than to sit in traffic.
I'm just sayin.
