What was the last piece of paper that you folded, why did you fold it, and why isn't the past tense of fold "feld"? ~

It was a parts list for the truck.  I'm doing wheel bearings/races/seals, brakes, and shocks all the way around, and tie-rod ends on front, which means I'll have to set the toe-in (1/16").

Is there a reason for the past tense of 'fold' to be 'feld' ? This post was edited by JakobA the unAmerican. at March 3, 2018 9:48 AM MST

I give up. Why?

An invoice.
To place in an envelope.
No idea.
