Well now days, I'm a DM, Player, Parent, and now Grandparent. My two adult children are out of the nest and involved in D&D (my son more so than my daughter).
When I first started playing D&D in high school (late 70s; early 80s) my father soon began to dislike the game due to the bad press. In fact, he never could get the name right...he would say "Yaaa boy, you still playing that...that...Dragons and Dungeons". For a while, I resorted to hiding my D&D stuff under my bed. My mom would sneak me new modules for my birthday and holidays.
Years later, he ended up moving in with me so I could take care of him because of heart condition. During these years, he accepted my hobby and even suggested that I write some material myself. He would often drive me to the local hobby shop and would venture in to look around. He never once played, but before he passed last year, I noticed that he was very mellow and very accepting of 'Dragons and Dungeons'.
