While I agree, there’s also a risk in letting the hypothetical family cause alarm about something false around electricity or whatever (misinformation).

So… you sound like a nice dude, so just so you know, there are people in the goth subculture that do not appreciate that joke (and its translations). For different reasons, but the majority find it fetishizing and sexist. I opened saying you look like a nice dude because I don’t think that’s your intention, or the intention of most here commenting, but that’s how many goth people feel and… well, in case you really want to meet goth people, that might be actually causing the opposite effect (that is, your shirt driving them off).
