So, hold on.

Superman is Supes, and Spiderman is Spidey, and Captain America is Cap. Okay, so far so good - but does Batman have a fan nickname? Besides "The Goddamn Batman", which, let's face it, is more like a title? I tried googling this crucial issue, but what I got was more a list of modern kennings* than affectionate nicknames.

* Well, if we stretch the definition of kenning a little.

We were doing geography earlier

And we were discussing the problem of longitude. I said - carelessly, not thinking much of it - that longitude was like the space race of the day. I got a full three sentences in before I realized that that phrase was completely meaningless to the girls. Even once I backtracked and gave them the historical background, it had no emotional resonance whatsoever.

Even by my generation, I guess that was all in the past anyway. The exciting parts, I mean, not the useful weather satellites and cell phones and all. I was not yet three when Challenger exploded. I don't think Jenn even has any memory of that, though I could ask her.

I wonder if "the race to be the first person to Mars" would work better as an analogy? Or maybe "the race to fix global warming" (if I thought we all took that seriously)?

Ana and Eva are in the living room

Eva's doing her science, Ana is doing Russian Duolingo (her own initiative here) and I pointed out that if Ana wants to work on something on the computer while Eva is doing quiet schoolwork, she has to either put on headphones or go in the other room.

Ana: Oh, headphones don't compat with this computer.

That... is an extremely nifty neologism. I like it!
