I do get confused with most speech. someone will say "you are so.." and I don't
know if they mean "you" as in Thou,
I do find the second person usage helpful
Thou Second person singular, archaic -
Ye Second person plural, archaic

As sometime I can not tell if the speaker means 'just me" or "just the other person' or
both of us, or all present, or everybody'.
third person may have some benefit with but I am not sure what it does.
