What is a a dumb thing you did but you are glad that you did it?

I'm not sure if I have really done something like this but the closest I can think of is the one time I was curious about one of my best friend's secret (She left our school before she told me). I was really curious and my other best friend let me know, since I was the second person to be best friends with her the longest (even though she treated me a bit unfairly and we weren't always on good terms). The secret was that she had two dads, my dumb mind thought "oh so they are gay. There's nothing wrong with that, they are just part of the lgbtq community" but it probably meant something like her mom got divorced especially since her mom was pregnant. I said something across the lines of "There's nothing wrong with having two dads, they are part of lgbtq community-" then I get told that she also has a mom, then I also get a sudden realization. I just feel proud because I'm not homophobic, it's not an achievement but it feels nice knowing a piece of trash like myself can at least accept people. Sadly, the topic of minorities reminds me of my mum being racist. She had a bad childhood (and probably a bad life itself) but I hope she isn't holding onto those beliefs still today.
