Quit Kissing Me Satan

So recently I have been working through a student who is choosing a life of serving self and what it looks like for me to lovingly/Biblically confront them. Also watched a tv show where the main character, who was a doctor, was dealing with being addicted to pain meds and I watched as his friends and family tried (horribly i might add) to help him by confronting him on the issue. Finally Skip said something on Sunday that sparked the same confronting sin thought process in my head. All of that wrapped up with what I had read in Proverbs 27:5-6  
Better is open rebuke
Than love that is concealed.
6 Faithful are the wounds of a friend,
But [a]deceitful are the kisses of an enemy

Now at first I thought these verses were for me on how to confront others on their sins but then God hit me with "How would/do I act when someone confronts(tries) me on on my sin?"  In a perfect world I would say "oh thank you, you are so right, that is very wrong of me I am so glad you brought this to my attention, can you help me with this issue?" However more often then not I probably don't even have an approachable spirit and when people do confront I will tell them where they can stick their issues (just kidding, sorta :-).

So the questions for me, and in turn for you, do I have an approachable Spirit? How do I respond when confronted with the sin that IS in my life? How do I view wounds from a friend and am I being deceived by kisses from the enemy?
