I stretch through time, not just through space, a quiet thread you can’t replace. No map can hold me, line or way, I’m what unfolds from day to day.

I sit close with many of my siblings Plucked when ripe from hanging gatherings Pressed and left to slowly age Then poured into your glass to raise

I am many things with many tasks, I swim with sharks and grade the flasks. I summit mountains, I model towns, I measure disasters that bring both down. I rise and fall in musical call, And sometimes I ponder the weight of it all.

My name sounds like a child's toy on a shelf, Joined with a fish's tool for steering itself. I live in a school but I never pass tests, I click and I whistle with air in my chest. What am I?

Yesterday’s Tomorrow is where you will find me. Time will tell.
