So if I'm rockin' out on my earbuds and am fidgeting/dancing around and letting out a little whoop and/or singing along, is that a faux pas?
I tend to get lost in my music, so it probably has already happened, and will happen again. Historical performance is indicative of future results, in this case.
It might just be a fun social experiment.
"Hey, it's that singing firewall guy."
"Yea, he's weird."
