DO you think that in public everyone (very subtly) is acting, different roles for?

Absolutely. People are acting way more often than they know or would ever admit. Funny though how if you give a script to some guy who you know to be very good at acting different to his female peer, his parents, his boss, etc. How bad of an 'actor' he can be ;-P Many people can't apply the sam principals of those things that they do on a daily basis to that person on the page. Make that person come to life with what you do every day with one of those other people that you relate to or whatever... use what you know, know what I mean?
