December First-ness And I-talians

So I was walking home one night after work, down Center Street where a number of bars and restaurants are located, when I passed by eight or nine people speaking Italian. They were quite loud and fairly drunk and nearly obnoxious and exactly what downtown Rutland needs at night (i.e., life). As I passed by however, without thinking, I murmured "Scusi" and kept walking. My question is:

Do I subconsciously know Italian, and if so, does it only present itself in situations where I am around the language and try not to think about knowing said language, and if so, how awesome is that?

And now, further slightly racist photos.
