Presence

If you ever travel, I hope you will quickly learn that people will do many great favors for you, because most people are filled with kindness and are happy to have the opportunity to love humans.  You might also learn that they aren't worried about you doing nice things for them.  They would prefer you to do so for someone else.  If you are lucky, they will also tell you that "your presence is a gift."  I say to all of my family, all of my friends, strangers, and students, especially all of you I've seen recently: thank you for the presents of your presence.
