Question

Which of the following is NOT likely to be an early sign of a damaged relationship?

a. Your cousin comments that you and your friend don't seem as close.
b. Your friend suddenly explodes in anger at you for no apparent reason.
c. You begin to feel a sense of discomfort with your friend.
d. Your friend begins finding excuses to break lunch dates with you.

Answer 1

I would say that it's this:

a. Your cousin comments that you and your friend don't seem as close. -

all the remaining answers refer to a process or observation that actually concerns the two people involved in the relationship, while in a) it's an external observer, who is not likely to have the full picture.
