The Phrasebook

“Good news, everyone!” is not the kind of thing you’d expect in a traveler’s phrasebook, but it’s right there alongside “Can you please direct me to the nearest vapor reclamation chamber?” and “Please do not consume my moltings.”
If you think it’s tough working up a list of common social situations between two vastly different species, then I’m pretty sure your mind will rattle and explode at the thought of having to construct a phrasebook for pandimensional travelers.
The truth is, it’s not hard. “How do I get home” is pretty much all you need.
Otherwise, you’re pretty much fucked.
