Worth noting: telepathy is a one way communication, as far as I can tell, not a mind-meld.
not at all...
The creature can mentally communicate with any other creature within a certain range (specified in the creature’s entry, usually 100 feet) that has a language. It is possible to address multiple creatures at once telepathically, although maintaining a telepathic conversation with more than one creature at a time is just as difficult as simultaneously speaking and listening to multiple people at the same time
Format: telepathy 100 ft.; Location: Languages.
it uses the word "conversation", it is two way communication, just like talking. if the other creatures know you have telepathy and are in range, they can reach out to you and "ping" you to talk. it is very good.
