I get freaked out when anyone touches me for any reason. The amount of times I have caught myself with a fist or slap an inch away is horrific. Luckily I haven't failed to catch myself yet.
I tend to carry two large cases, one strapped to each arm to carry stuff in; easy weights and decent shields should I get into a fight. -surprisingly common where I am.-
I listen in to a lot of conversations; generally people freak out because I know stuff they think NOONE ELSE knows about, as I heard it as they spoke under their breath, or they whispered it to a very close friend.
It is rare you catch me out and about without both a suit and a coat on, usually with the hood up raining or not.
I often keep a hobby knife on me for my wargaming; not too odd but I have it on me even when I'm not planning hobby stuff for some reason.
Every book I own has the letter "E" beginning at least one word in either the book title or author name.
I keep random disks of green plastic, a tape measure and a box of 27 dice in my pocket at all times.
I feel like I should continue, but I won't.
