I am more than mere ingredient hoarder--I'm an ingredient klepto. And I've snatched so many flowers from shrines I'm surprised the Divines themselves haven't smited me down. Garlic braids are my biggest weakness.
I tend to hoard "free" food, especially meat and cheese from wherever I can find it, even if by pickpocketing or rummaging barrels. I confess I recently picked up a cheese wedge that was lying on the floor of a falmer den, and thought, "Yeah, I probably ought not eat that..." I also recently pickpocketed Jon Battle-Born and found him carrying some butter--and butter's prime food item for me--but decided I really didn't want to now what he had been using that butter for so I left it on him.
I tend to sprint through cities, especially Whiterun, and often rudely plow into NPCs who usually make some vocal objection.
I take shortcuts over walls/rocks/ledges and then have to wait from my follower to catch up to me because they have to take the "proper" route.
Whenever I visit Half-Moon Mill, I yell "I know you're vampires!" at the screen. I hope that wasn't a spoiler for any newbies.
I have a definite system for storing things, and will use that same system with each character so I don't confuse myself with where I store things. I once thought I lost the Wabbajack in my battlemage's game because I didn't put it in the upstairs chest like I usually put all unique items and after going crazy looking for it , I eventually found it storage in the end table where I store alternate sets of armor and weapons. This is why I have a system!
I always, always store stolen items to be fence in my housecarl's room. That way I can blame my housecarl if anyone comes looking for their stuff.
PS: "Smited" is perfectly fine online snark-speech, BTW.
