None here. Never got married because of knowing that most years of my life I couldn't afford myself let alone a wife - and thankfully even in my drunken/stoner years I was never stupid enough to knock up a gal I was shacking up with.
I wouldn't call this "The Plan" - it just worked out that way is all.
Ironically in my near retirement years, I've become a school bus driver - and for the most part I get along great with say 90% of my 100+ kids. They sort of look at me as their cool grandpa/uncle they've never had. I sort of look at them as kinda like a "what could have been" thing.
Each summer is difficult - I miss them, even the hard cases. Fortunately I get to see many of them during the summer on sports/summer activities trips, bike riding around my neighborhood, etc. Often this summer I'll see them during these and they'll haul me over to meet their parents, like I'm a "show and tell" ornament. I get a lot of "so, you're the school bus driver we've been hearing about" from parents.
Crazy really. My friends when I see them marvel at me doing this for a living. I get a lot of "I never saw you as a bus driver...you HATE kids" kinda thing - which is odd because I've never hated kids so much as knew I was never the family type.
Strange...where life takes a person through the years. And honestly...I got all the kids I can handle currently
