No, I don't introduce myself that way - that would be crazy. There is a popular theory that the handshake originated as a way to show your hand wasn't holding a weapon. I think the evidence for this history is shaky at best, but it's been repeated because it's somehow a compelling idea -- what were people thinking many hundreds of years ago when crime was so common that you genuinely wondered about whether you could trust a casual acquaintance not to hurt you? What did they do to protect themselves? It doesn't seem unreasonable to wonder about how to present yourself as "safe" in the deeply untrustworthy home-sharing privacy landscape where casual home surveillance is ultra-common (and where neither landlord nor tenant knows how much they can trust the other). I'm not sure there is a good answer and it's not crazy to try to look for one.
