<human>: So basically some people (myself included) sent a fake email to someone that we thought was pretty funny (not A-grade laughs, but something we'd giggle at if we received it). Anyway, they figured out who it was from the style of writing and seems to be offended by it, outing us online in a bit of a rant. The content itself wasn't offensive, however they seem to be insulted by the idea of the email (i.e. that it wasn't serious).

To be honest, I'm a bit unsettled at this action, let alone personal response to the message. I don't like to get on anyone's bad side, and can't quite tell how serious they are being about this, but the fact that they used names instead of approaching us privately has me nervous.

I've been in a group chat with these people (and others) since, but don't see them very often, and am yet to talk about it with them. If it did ever come up in conversation, I am sure I could plausibly suggest that we didn't do it, if not for keeping a straight face.

Am I making a bigger deal out of this than I should be? and should I bring it (my response and theirs) up with them? How?

Can you condense the text into three sentences or less?
<bot>: quiet guy got called out on a harmless joke and extremely embarrassed. could i forget about it if they don't bring it up, or... what?
