Thank you. One non native English made me confused and said:'The double possessive is a matter of some controversy. Some insist that constructions like 'a friend of Bill's' are redundant and therefore should be avoided. Others see 'an old pal of mine' and extrapolate that, because you'd never say 'an old pal of me,' you also must reject 'a friend of Bill.'
As written in this link: double genitive - definition and examples of the double genitive
He told me, according to that link:
Alex is a friend of George is incorrect and Alex is a friend of George's is correct.
Is he wrong?
It doesn't for native speakers.In this sentence: "1. Alex is a friend of George's." leads to the question, "friend of George's what?" Is Alex a friend of George's mother, George's friend, George's Aunt Mary.....
You'll just have to accept that this is how English works.You see my confusion?

You see my confusion?
The same is true of My sister's/sisters' friend.A It can be confusing: A friend of my sister's sounds the same as a friend of my sisters.
The same is true of My sister's/sisters' friend.
We somehow manage to survive these little hiccups.
