I used to have childhood friends just like this, but I kept going to their house and before cell phones, you would literally walk to their house and knock on their door, there were no cell phones and calling ahead just wasn’t a thing yet.
But I guess it was the equivalent of ghosting back in the 90s because she just never answered the door after I turned 11-12ish. I kept trying over and over tho. Guess she was just really creeped out this chubby 12 year old still wanted to be friends. When I obviously was crushing on her. It must of been disgusting
