I'm a little bit torn. The story seems familiar - I almost get the feeling that Jiro's told it before. I looked up the retirement home Jiro mentioned and his descriptions of it seem to mostly check out (of course Jiro could easily have looked it up the same way I did). I've been leaning towards truth for most of the round. The biggest technical hitch I can see is the table-with-benches construct which I can't see in any of their pictures despite several outside seating areas being shown, and which seems like a strange choice for an elderly home if you have to climb into them.
As far as the non-technical side of it goes, it seems credible enough. Jiro's description of his personality is certainly accurate.
I'll give TB a chance to give her final say before I put the official vote, if that's okay.
