Gaming

Indeed. I do use the fus sometimes to buy me some time, and the sprint one to reach places, but that's about all of my shouting too.

But vampire or not, I prefer not getting hit with sharp things and killed in seconds.

I liked the fire breath thingy until I got the three word FUS...
Once you have that you don't really need any of the others as it throws people around enough to give you time to kill them while they're trying to get up.
I remember using Slow Time once when I wanted to race through a Giants' camp to steal something without having to bother fighting them all.
I still have problems trying to kill Mammoths so I'm extra careful around those camps.

Turning them into an ice cube is fun though. Then you say something like "Chill out!" and laugh to yourself at your amazingly clever pun, then you kill them, and next time you can use a different pun like er... like... "hey, you seem like an ice guy... an ice guy, like a nice guy but you know, ice because you are frozen now" erm... 

So... I'm not the only one talking to people in Skyrim?

"That's snow way to treat a friend. Snow, because it's kind of like ice... ha haha oh... sorry I have to kill you now so you don't tell anyone what I just said" 

I tend to go with the shorter "shhh" when followers blab while exploring a cave system, or "hello" when someone says "hello friend" in passing. Or just "hmph to you too" when they say hmph. Occasionally I might expand into "Yes, you would say that, wouldn't you" and similar... I think my repertoire might be as limited as the NPCs...

I actually don't say any of that stuff. I just swear at the little brats that hurl abuse at me in the street and threaten to kill them to death 

The "I'm not afraid of you!" brats or the real life streets?

Was that a yes or a no? Wait, it wasn't that kind of question. What was I asking again?
