You really look like an English!

Since I was a child, I have always been meeting people telling me: "You look like an English!".
It was partly because of my white complexion I think or my blonde long hair and partly because of my attitude in life.

When I was in Northern Ireland, collecting books and info for my thesis, a professor of the Faculty of Science, breaking into the room where I was talking to the secretary, said "I know there are two Italian girls here!". He shook my hand vigourously and he added: "Your friend looks like a Spanish, but you do look like an Irish!"

Last but not least, two friends of mine who, I suppose, have never been to UK, told me that "with your detached attitude in life" and "with your pale yellow dress and your bag, here, in the wood", ... well I looked like an English.

But what does to look like an English exactly mean?
