here is something for you all to think about:
wrong is the opposite of right <== true
left is the opposite of right <== true
so both left and wrong must be the opposite of right, so they are the same thing.
going from that we have the old saying:
"two wrongs dont make a right"
well, since wrong is the same as left, it can be said:
"two lefts dont make a right"
this still comes out as a true statement, thus further validating that wrong and left are the same thing.
but here is the twist: two lefts dont make a right, but THREE do!
"three lefts make a right"
that being said, we can replace left with wrong again, and we get the statement:
"three wrongs make a right"
the moral of the story is, if someone does something wrong to you, you must do, not one, but TWO wrong things back to that person to rectify it.
