if you think English is confusing, you should try Welsh (Cymraeg ) ....
English used to have more than one word for "you", well actually, in some ways , it still does, it's not like it lost them behind the sofa, it's just that no one uses them.....
so "You" has become the default common use option, that everyone applies , even when other words, such as "Thou" might be more appropriately utilised.
but these days "Thou" would just sound silly..... no one in general population has used that in normal conversation in probably more than a 100 years.... we all still know what it means, and recognise it as a more formal version of "you" but no one uses it.... we are the proletariat , no one speaks linguistically with formal implication of inferior status ......
god i can't half talk some dangle berries when i feel like it....
