In the example of returning a lost dollar bill to the owner wouldn’t it be better to say a lost wallet as finding the owner of a dollar bill is impossible?

In your last topic which states: If a man finds a hundred dollar bill

on the street that it states if the man finds the person and gives it
back then he is honest and wise” However that makes NO sense
whatsoever as it sounds ridiculous. I think your writer could have
worded it as a Wallet with money in it, INSTEAD of a bill on the
street. My question is: HOW CAN ANYONE KNOW WHO THE MONEY CAME FROM AS
EVERYONE WILL SAY ITS THERES AND HOW CAN A PERSON LIKE YOU STATED FIND
THE PERSON WHO OWNS IT……..THIS MAKE RIDICULOUS
SENSE……………..I know what your trying to point out, however
not using that kind of a sentence that makes no sense. Hope you know
what I mean.
That sentence used should NEVER be used as there is NO common sense in
it whatsoever.  Namaste.
