Send someone flowers who lives far away with a nice card reminding them how much you care. (This has a similar effect to black-tar heroin on mothers/mothers-in-law/grandmothers.)
People with kind hearts make me feel dirty. Like I need to give my personality a bath or something. Rub it clean of my neuroses and judgments. But that’s a good thing. When someone inspires you to take a long hard look at yourself and question all of your bad habits, they’re someone worth keeping around.
I recently held back someone’s hair while they vomited for the first time and was struck by how tender it felt. Scooping their hair up and pulling it back as they do this really disgusting and vulnerable thing felt like a total bonding experience. Added bonus points if you massage the back of their neck while they heave.
