As far as my life in the real world that I have to live goes: bitterly disappointed. As far as my sense of identity and beliefs go, happy. But also disappointed that I only got to this point when it basically seems like it's too late.
I just hope that in this hypothetical situation where my 15 year old self gets a glimpse of me now, that it causes my 15 year old self to do things differently and have a great life in a parallel universe.
Not me but a guy I knew used to have peanut butter and mayonnaise sandwiches. I tried a bite and it honestly wasn't as bad as I thought it would be. Not the kind of thing I'd make for myself though.
