Since this is a "support" site, I think it's best we do what we can to show support of the individual without being critical or judgemental. Everyone's lives are different, everyone is in a different place in their recovery.
That being said, there is nothing wrong with asking an individual if they are interested in your opinions and/or life experiences. Keep in mind that some of us are looking for others ideas and experiences, but we should not force ours on them. Being respectful to everyone is of the utmost importance to keep this site exactly what it is meant for... support!
Sometimes it's hard to know exactly what would be accepted and what wouldn't be accepted. In those times, ask if they are interested in your take on things.
