My current character always leaves a single nightshade flower on the rapidly cooling corpses of any member of the Dark Brotherhood that is foolish enough to attack her ( she also leaves the contract). She will always make sure to carry about ten of them on them, so she is ready for the next vain attempt upon her person.

My assassin-type character is a compulsive liar. Whenever speech options pop up, I choose the least truthful or vaguest one. She also never fails to play a game of tag with a kid whenever she stops by Solitude, even if she's there to perform a hit. My hunstman, on the other hand, can face down a frost troll without so much as blinking an eye but is an absolute coward when it comes to draugr, skeletons and ghosts. His approach to tomb-like dungeons is to run until he stops seeing dead things or his lungs give out.

No real quirks per se. Although when I save and quit for the day, I find a cozy spot for my character to hang out until I'm back, I never leave him in dungeons or out in the wilderness at nighttime, etc. And when he's set I put it in third person for some reason too.

My character is in search of giant women to romance and marry

i second the tag with the kids thing. hide n seek was fun but the kids are almost as dumb as my nieces and nephews and hide on the same spots over and over again. i say almost as dumb because at least the skyrim kids dont announce where they are hiding. this is a case of video game AI being smarter than real life "AI"

for my ingame charcter im a loot hoarder. i collect everything i can especially crafting stuff like ingots and then i make all of it into weapons/armor and then i enchant it with all the soul gems i picked up along the way and sell them. unfortunately im swimming in money after a bit with nothing to spend it on except potions.

My character tends to just look at the faces of the people he killed after a battle.

Depends on character. My Thalmor agent who was also part of DB always murdered at least one guard when he passed trough Falkreath - until it ran out of guards.

I always take all Ebony weapons from the undead and at the end of the dungeon i'll drop all of them in front of the word wall... or just the end of it. i know.

After a battle with bandits or other humanoid characters, I pose them to make it look more awesome than it was. I usually have one slumped against a wall with arrows sticking out of him and another dangling of a nearby edge.

In one particular quest, where you have to rescue a child, I always hide the bodies out of sight. I didn't the first time, and every time we passed a corpse she'd scream " Ah! Dead bodies!"
