No different if your giving the honest criticism they need along with the help they are asking for/need.it also depends on if you are really that close to them to know what they need to hear in order to motivate them out of the sticky area they are in or past the point they are getting hung up on.it also depends on if it is really necessary for you to how shall we say climb on their shoulders/back to make them listen.in other words it depends on if they will take it as you being helpful or hurtful when you give this feedback. If they really know you and that your trying to help then all you can do is give them your honest opinion.they will eventually have to see it/get it for themself.as the old saying goes you can lead a horse to water but you can't make them drink.or you can pick your nose but you can't pick your friends nose.: )
