Про разницу между Was и Were есть очень хороший анекдот. На русский его
не перевести, заранее прошу представителей неанглоговорящих меньшинств
извинить мою неполиткорректность.
A zebra died and went to heaven. When he got to the Pearly Gates he
stopped and asked St. Peter... "St. Peter, I want to know one thing but
nobody is able to give me the answer. When I was alive, were I white
with black stripes...or black with white stripes?"
St. Peter said: "I do not know. Ask God."
The zebra approached God and asked: "When I was alive, were I white
with black stripes, or black with white stripes?"
God answered: "You were what you were."
The zebra went back to St. Peter and said: "I'm confused. He told me:
You were what you were." "Well!", said St. Peter, "you do have your
answer! You were white with black stripes!" "How do you figure that?",
questioned the zebra.
If you were black with white stripes, He would have said, "You was what
you was!"
