What an up-front write, Alex.

1/ I think you are right in generalizing that we all wear masks cause' I really won't believe that no one ever did. Given different cases, we may have different faces. Ha!

2&3/ A tough question! I guess yes we have more chance to get to know somebody fully when we are physically with them. But if we barely are together and especially now we just communicate thru technologies we may not know if what we know is just their facades.

A write that leaves you asking. :-)
