Ravenclaw:
reading funny/interesting facts and forgetting them right away (except for the VERY fascinating ones), going to a foreign country without knowing the language; learning as you go/by experiencing it yourself and through failed attempts, multitasking (with questionable results), space, tearing paper as a stress reliever, preferring ballpoint + mechanical pens because the line they draw is even, procastination, blushing easily, either REALLY neat or REALLY messy handwriting, making sure everyone is drinking enough water (and not too much alcohol), never borrowing money but always lending it to others (with no rush to get it back), wind, green tea, talking really fast/loud when you get excited, laughing and smiling silently, only paying attention to the things that interest you

Hufflepuff:
sunflowers and dandelions, (cookie) dough, colouring books, choosing the slightly smaller half of a halved pastry even though the other person said you could pick either one and they'd have the other one, bumblebees + honey bees, listening to loud music with headphones and constantly fearing others can hear it, humming and whistling, coffee and hot chocolate with lots of whipped cream and spices, blanket forts, not feeling pressured to do anything "productive", always thinking it's your fault (it's not), having days for yourself; peace and quiet and self-care, movie/TV/Netflix marathons, procastinating at first and then working for hours and hours straight just before the deadline, rain (heavy or light), chocolate and peppermint and fudge
