Im curious about if your characthers perhaps have some weird hobbies/personal quests/work? Something that stands out from the "normal".
In oblivion I had a character that was obsessed with collecting cloths and store it in his house. It ended up with that the basemant in his house in Skingrad was full of clothes and boots. And I dont mean armour, I mean casual clothes.
I know that I will create some kind of farmer who lives out in the woods and makes his money by chopping wood, hunting and smithing and then travel to the nearest town/village and sell it. He will do some small sidequests, sur, but he will not be the adventuring type.
He will live in his farm with his wife and grow crops, hunt and sometimes travel across Skyrim to pay his respect to the different temples of the nines.

Please share if your characters do something unuasual, I want to know

I will at some point roleplay some crazy man who has no idea how to use menus and thus is stuck at level 1 in his starting gear punching things for all eternity.

If at any point there's a quest where he's required to open his inventory (such as in the beginning, to give that axe a few swings) he will have his fisty vengeance on whoever made him do it.
