How does Batman do the disappearing thing?

How does Batman disappear when he is talking to people so fast? I know that he was trained in Ninjutsu as a Ninja and stuff but is that a real technique?How does Batman do the disappearing thing?
who knows? if we knew we'd all be batmen and batgirls!How does Batman do the disappearing thing?
maybe he finds a good hiding spot while he's being quiet...

then lays down his bitchin' line, waits for the other character(s) to look away and bam, he stealthily slides into the hiding area...



it's not like people search for him or anything..

they just find out he's gone and then awestruck at the fact that batman left while they were talking, wondering where he learned his manners from.How does Batman do the disappearing thing?
Hi.



There are a couple of reasons:



1- Yes he was Ninja trained, so how he got there is how he got out.



2- It is a plot hole and something that is needed to keep the "image" of Batman intact- can appear at any time.



All the best.
