Q: Did something happen recently that u regretted and what was it

A: we have to define regret first, i think. or the experience (phenomenology) of regret. this is a bit ad-hoc (put together on the spot) but to me, the phenomenology or experience of regret sounds like:

if we accept that as a reasonable definition of the experience of regret...yeah. i have regretted a lot of things! even recently! but not for very long. i treat regret like other emotions; they're a signal for me to pay attention to something. if it involves another person, i try to apologize as soon as i recognize i fucked up.

i try to figure out why i'm feeling regret, if i could have done something better, what i could have done better, how i can become the version of myself that does the better thing. then i try to learn whatever i need to learn to avoid repeating the regretful situation. after that, there's no need to hold onto regret. i let it go. it's replaced with a resolve to do and be better in some way, big or small.

i can't be more specific than that, because anything i have cared about enough to feel regret about is probably very private and personal. if not for me, then for other involved parties. and i do look back on moments that used to fill me with regret and feel incredibly sad sometimes and still feel deeply ashamed of myself for not having been a better or wiser person at the time.
