Impossible ?

On Father's Day,June,2017 I learned that a good  young adulthood friend of mine (who I referred to as my 'little brother')  had died in 2014. Since and up until today I  belatedly mourned the loss . This evening I
sought a sign of consolation that everything is  alright with him  and recalled our inside joke of using the word, "impossible" when we were exasperated  or thoroughly amused by something.
I decided to search for a clue of his current well-being  by  looking up a definition of the word,IMPOSSIBLE. There were several definitions but only the following one fit the circumstances at hand-
