C'mon, I know you have them. At least one.

I collect gloves. Not the crafted kind, the no_armor cloth kind. Simply because they're so rare compared to other clothes and because I'm still waiting for a mod that lets you wear them even with braces on. Because, you know, they're gloves. You should be able to wear them when your hands are bare.

I can't help but collect every possible sweetroll I come across.
What can I say, I've got a sweet tooth... and possibly a deep fear of my last one getting stolen..

I have an awful time selling potions because I always think I'm wasting something useful...therefore, most of my "junk weight" is always in potions that I never ever use. I know that I RARELY use stamina buffs/replenishers but I keep them all anyway I haz a problem

I jump. a lot. its a bad habit I cannot kick from my old WoW days. I also try to run as many circles as I can around NPCs when they are talking to me and especially when they are asking me to follow them somewhere.

I have a drawer full of 'Shiny Objects', including Silver Weapons and tons of jewelry and other useless junk that sits inside my house in Markarth.

I have a hard time passing up any food or plant.Half of my inventory is make up of edible things or potions/alchemy ingredients.I'm always afraid I'm going to get into a huge fight and die because I have no food or potions.

I've always collected helmets in every game, preferably lining up one of each on a shelf.

I did that in Oblivion.All the display cases in that one house had helmets in them.

Oh my GOD, I know that all too well!
