I like to hc / think that while doing a mind transfer takes a lot + signs, yamanakas once they get a hold of the techniques are able to sort of.. push/project their thoughts onto someone easily? like example, having wanting to tell someone smth but not say it out loud? use some chakra and sort of connect your thoughts for a minute. it's tricky if someone actively resists but otherwise it's fairly easy.
people talk about how the yamanaka clan always seem to know what one another are thinking just with a look, but it's literally just the fact that everyone can be telepathic basically after training. they are having conversations in their THOUGHTS.
anyways. thinking about ino and inojin having gossip sessions out in the village with telepathy. they keep giving one another looks of surprise.
