This question already has an answer here:
I've never thought about it but now that I think of it..
In this conversation for example :
Person A : thanks for coming.
Person B : no problem.We fishermen have all the time on our hands right now. There're so few fish these days, you would think the sea was dead.
To who refers the " you would think " ? The conversation partner (A) ? But that is just what B think why would (A) think that ?
People always use "you" instead of "I" when speaking their minds to someone even if they're talking about themselves. Why?
" A: Why do you you go that place?
B: that place is the best place in the world YOU don't get bored there there's always something to do." Why not I don't get bored?
