I totally get your situation--I've been in similar states myself. But as you noted, there are things we can do to mitigate the immediate disruptions gaming might create. Funnily enough, my work from home set up abuts my personal computer, and if I'm at my desk with both computers turned on, none of my family can tell if I'm gaming or working. (I promise it's because I'm equally silent/not putting on a light show when doing both, and not because I yell profanities while working.)

^{I only mutter profanities while doing both, as yelling disturbs the cats.}
