The best way to talk to anyone and everyone is to be your authentic, natural, and genuine 'self' at that time in your life (whatever it may be)... When people try to adopt a certain way of talking/behaving in order to make a specific or desired impression upon others (usually the opposite sex) - they'll never be able to feel comfortable in their own skin because they are not remaining true to themselves. It's like they are putting up a front, playing a role, and 'acting' in order to obtain some imagined favorable reaction/response. This doesn't work out and does not lead to feelings of contentment, acceptance, and peace of mind.
