CaMOfo may like to talk in third person but Yoyo likes to combine first, second and third person in one sentance, unlike you.
First person is I/WE Second person is YOU/YOU Third person is HIM/THEY And yes, second person is used most often for persuasion.
Since I live in Texas I hear a lot of "Y'all" for second person plural. Me, I can't say it without feeling foolish.
