I def was a latchkey kid
I'd have the crib to myself for about 5-6 hours. Parents would give me an allowance + go on massive grocery shopping haul, to make sure I had plenty of food at the house.
Social life wasnt a problem, I got plenty of that during school hours + I had a shyt ton of friends in my neighborhood; My street alone was packed with friends/family and our parents all knew each other; true community. My parents crib had the the biggest yard on the street though (Massive front&back)
so naturally all my friends wanted to play football and shyt there and had to go through me (Just dont hit or lean on my pops Lincoln or Ma's BMW nikka

)
If I got tired of playing the Playstation/Sega Genesis I could easily go outside and find plenty to do with friends. I cant stress enough my street was littered with kids so I was wealthy with friends, especially being the hyperactive class clown I used to be lol.
I dont think it made me a lonewolf, I jthink I was born with a high capacity to be alone for long periods of time unbothered. But I can be social just as seamlessly
I do think being a latchkey kid made me self reliable and not take people's trust for granted (having to cook my own food and being trusted not to burn the crib down or let people in the crib before parents got home"
I had to mature quickly because even though I was given alot of freedom and autonomy, I had to be responsible with those as well. And it wasnt like I could just call them on their cell back then, because their were none until beepers came along. I had to figure shyt out.
wouldnt change a thing though, life was still good back then
