It's also reasonable to assume that there are only "so many things" you would say when meeting a new species for the first time. Also, in the case of Star Trek, by around TNG, humans had already encountered most of the space faring races, and had spent some time covertly observing the more primitive ones. I think they mentioned in the Darmok episode that they'd had encounters with them before that'd gone badly.
