Otherwise, it's a smell on the landscape...or footstep on the beach...or tree that grew from a seed you planted sometime long ago, to give shade to a stranger you will never meet.
No matter which, those who stick around a little longer will see something and say to themselves: Tom was here. He's looking through my eyes right now at what he saw back then. Thanks Tom for showing me something I didn't see before.
Or rather, that's the way it is right now, young man.
Cheers to you!
