I do have skill at sneaking, but I often use it without particularly meaning to; when I was younger, I had a few older friends who were interested in martial arts, and we would often play a game that we made together; it was for two players. Essentially, it was akin to Marco Polo on land; one person wore a blindfold and closed their eyes, and the other wasn't allowed to stop moving for more than five seconds or climb any trees. By feeling for vibrations in the ground and listening, the blindfolded one had to catch the one who was sneaking. We played it a lot and had a lot of fun while sharpening our senses and building our silent movement skills. (My silent movement skill actually also applies to in water; my four brothers and I are probably professional level Marco Polo players, judging by the skill level of the amateurs in the neighborhood who we could sometimes trick into playing with us.)
Unfortunately, in my adult life this has generally led to me saying something and a person practically jumping out of their skin, since they didn't realize I was standing right there. They tell me to stop sneaking around, and I tell them that I'm not trying.
In conclusion, if I have a sneaking skill, it's pretty high intensity at least and I use it pretty much all the time without thinking about it, and I'm not the type to argue and try to say I do if you say I don't.

I walk up to the suit of armor that looks highly stylized, and eye the wicked axe approvingly. Nice quality weapon.
I'm paying attention to the armors; do they seem to be watching me, or moving at all?
If I feel fairly comfortable, I'll take down the shield from the suit.
Do any of them have a dagger, dirk, or knife as a sidearm? That would probably be a better weapon than my butcher knife; I doubt I could use a longsword or a broadsword very efficiently; a rapier or a saber, or the other hand -- or a MA CHE TE...
