It's hard to explain what I mean but I'll try!
One relating to the future...I feel sad that I won't be around when humans inevitably connect with some other form of life or some incredible space discovery.
There's one regret I have about the past...That I wasn't around for the hippie era.
One that's kind of odd and I can't put my finger on why I feel like this but...I was a teenager in the late 90s/early 2000s and I always had this weird regret that I couldn't ever experience being an American high school kid or going to an American college. Nit sure why but that's really strongly connected to that era and my age then.
Just wondering whether anyone else gets these wistful thoughts!
