"Neither a lender or borrower be for loan oft loses both itself and friend."

Polonius said this quote while he was giving Leartes advice before he went to England. This shows how he cares about his son. What he means is that you shouldn’t be a lender or a person who borrows. Because when you loan or borrow then you end up hating each other because one always needs to collect the loan and the other always need to pay it back. This drives a wedge between their friendships and so they both suffer and then the loan is lost or just carried out for very extended periods of time. This quote definitely applies to the world to day because look at every one who is in a bad loan and getting for closed. For loan oft loses both itself and friend.
