After repeating the day’s schedule to my child for the hundredth time, I took pen to paper.

“Your basketball game starts at 11:15.  Coach wants you there 45 minutes early.  11:15 minus 45 minutes equals 10:30.  It takes about 45 minutes to drive there.  10:30 minus 45 minutes equals 9:45.  Add 15 minutes to make sure we have enough time and BAM! 9:30.  That’s when we will leave.”

Paper to pen time travel.  It’s a beautiful thing.
