That was a nice thing you did man. Its karma. Your nice to your gramps, take him out of the old folks home and get him high. Make his life happy instead of sad. And then when he passes away(tear) you find out he leaves all of his money to you and your kids. Youre a good man dude. Youre grampa died happy it sounds like. Thats good. Also on a side note, i read that weed is good for people with alzheimer's. Maybe thats why he was able to snap back to reality and think about today instead of 1940s.
