Dude, you're very lucky. My Dad really didn't have a hobby, except for maybe work. If he wasn't at work, he was at work in the yard or renovating the old house we lived in, always something to work on. No time for frivolous stuff like hobbies or playtime. Growing up we entertained ourselves as our parents had important stuff to do.
My hobbies sprang from inside I suppose, and nobody in my family does the things I like to do.
Fantastic post.I am lucky beyond anything to be sitting here at almost 40 and have my dad let alone my grandfather (who I flew for the first and likely only time a few short months ago and God I am so glad I got to do that).
