Atheist, I don’t understand your reference to meeting other people. Meeting them in what respect?
The notion of meeting loved ones in an afterlife is a comfortingly pleasant one. I see no harm whatsoever in that. However, whether or not it actually happens can only be a matter of speculation. That said, I've no doubt whatsoever that odd and inexplicable things DO happen in this life and although, in my opinion, religion has no part of it, personally, I can never say 'never'.
