I love seeing how people older to me dress. Esecially if they're around my grandparents' age. I totally check them out at bus stops, banks, supermarkets etc. etc. There's accounts of this theme that I also follow on IG, of the Chinatown elders and the Italian elders.
They are lonely and they canโt stand it, just like you or I might be some day. Go check in on them, help them figure out email, ask them about objects in their home, listen to their life story for a little while. its fun !
