My grandfather looked at me like he was about to say something when we heard the echoing smack of a fish jumping. My grandfather's face jumped a little and he looked around in the way he does so often these days. Uncertain and just a bit scared. Getting dark, Tom. Reel in and let's call it a night.
Some kids ride their bike, some hike, some listen to music.
I fished at night. As a kid, you need somewhere to go where no adults can tell you what they know about what you're trying to puzzle out. I never caught anything, just sat there at the end of the dock. I just fed them on my way back in from fishing. Gone, not coming back, no details.
