well i am a sub turned slave and i can tell You that the biggest tip off is, WHEN IN A PUBLIC SETTING AROUND OTHER PEOPLE, we subs, at least me and the other subs that i know, are louder, extremely opinionated, can almost seem bitchy. BUT WHEN REMOTELY ALONE.... if the sub likes You they will seem to have almost a completely different personality.... of course this is if the sub likes you...which is probably what You want, we become much more "outwardly-submissive" or we tend to try to drop hints in seemingly round about ways. When trying to test out a Dom we like to subtley do "submissive" things... i cannot name specifics but we definately DO NOT like to make eye contact when alone with someone else if they are talking in even a slightly dominant manner. But we definately will drop slight verbal hints... it can be a reoccuring tone of the stories that they tell... there WILL be a submissive undertone that is easy to see but hard to pin-point........

PLEASE LET ME KNOW IF THIS IS SOMETHING OTHERS HAVE NOTICED
i MAY JUST HAVE MESSED UP HEHE
