Little Character Things

This is where you come to help others out little by little. This posting is for "Little Character Things" that your characters do to make them seem more realistic. For example, one of my characters go out and does things relevant to the plot but always remembers to bring back a Snickers Bar for his older sister.
You can help by putting some interesting things you do that a character might like to do or see or think about etc.

SOME MORE EXAMPLES:
Does origami paper butterflies
Only eats the orange Skittles
Always gives an inanimate object a name (and addresses them by it)
Puts tape on the door handles because they don't like the feel

ANYTHING will work and anything could help someone else. Thank you for your time!

Loves oranges but makes other peel them because they dislike the feeling of the orange peel between their nails
Won't touch others feet
Will not walk around without shoes on grass
Doesn't eat food that other people have touched
Always puts their pants on before their shirt when getting dressed
Talks to themselves (not in a insane kind of way, more of like pep talking)

I like this idea, especially if each character gets multiple stuff like this!

Puts one sock and shoe on one foot before doing the other one.
Apprehensively touches anything metal for fear of static shock. (I do this)

yo, this is so important for characters and makes them feel real and life-like. We all have our little quirks and so should characters!
–won't eat yogurt or pudding because of its texture
–always closes the door behind them/always leaves the door open
–bites their fingernails
–won't drink ice water cause it's too cold
–always twitching/bouncing leg up and down
–spaces out and forgets where they are (i do this one all the time)
–hums songs under their breath
–collects weird rocks
–shoes seem to always be untied (this one is me too)
