Oh, I see.
This could get me started on something.

There is a need for English to have two distinct types of pronouns for the second person (one plural, and one singular) to avoid all this frequent confusion due to the currently ambiguous nature of "you."
We used to have them. We used to have thee and thou as singular object and subject pronouns respectively, and you and ye as collective object and subject pronouns respectively. If somebody said "how art thou?" we knew they were only referring to one person. But if they said "how are ye?" we knew they were directing the question at a group of people. Sadly, that usage is now archaic, and nobody knows if "you" means everyone, or only one person.
Some groups of people invent their own dialect and make up a collective pronoun. In Northern Ireland and parts of Scotland they say "youse." In parts of America they say "y'all." People mock those types of people, and say those dialects are common. But actually, what they are instinctively doing makes a lot of sense.
