It is nice to just touch onto the points which are telling,so so telling.  Sometimes we use the term HINT Hint as a clue, however there is another way to confirm ones best wishes as in COUNTRY MUSIC.  Rain makes crops grow and from the FARM, "I" was raised on a FARM and one of the term for GREEN was if the RAIN comes and if the crops goto market we will have food for cows chickens US "the family'!  The more CROPs to market the GREENER was the harvesting,, so you could say GREEN is a good thang as is RAIN!
