There'll be packages flying and pre-loaders crying and drivers stuck in the snow...
There'll be scary volume projections and tales of the agony of peaks long long ago...
OP, don't listen to any of these negative nancys. Peak is great! Think of the your favorite Christmas. Remember how happy you were? Remember that warm feeling of love and goodness in your heart? Remember that smile on your face? Good. Now think of the present you got that year. Let's make that item the physical manifestation of that Christmas. Now let's put it in a cardboard box. Oh no no, leave the bubble wrap and peanuts over there we won't be needing those. Ok, so now we got this cardboard box holding your favorite Christmas memory. Now imagine yourself with the box at your work area. Go ahead and set that box on the floor. Perfect, now step back. Good good.
Forgive me OP, I haven't been completely honest with you. You are now restrained by invisible forces. And look here come all the managers in your hub, but why are they carrying baseball bats? OH MY GOD! WHY WOULD THEY DESTROY YOUR FRAGILE CHRISTMAS MEMORY? Wait, look OP! All the people of the world that act like decent human beings solely during Christmas time (as long as they're not at the mall) have come to repair your Christmas memory! It's a Christmas miracle! ... They.. They just trampled and spit on your destroyed Christmas memory. They added insult to injury. Wow OP, I don't know if you'll ever be able to enjoy Christmas again.
And that's what preload is like during Christmas.
