Recently I did a friends request to an old friend who has a private profile.I never heard back so assumed I was rejected.One day I was bored and went to look at his profile and it let me in.How was I accepted or was I? I am confused.I am not on his list ,he is not on mine,and I never received any notice.I had a friend check,and he still has a private profile.Can someone please explain?I am new to all of this,and very curious.THANK-YOU
