I can share my experiences ,some listen ,some don't
I had to make my own mistakes ,sometimes others do to
it would be easier sometimes to take the advice
but some will do just the opposite just because "No one tell them what to do "
So it pays to know something about them
and if you care about them ,maybe you do know enough to give sound advice
but some people are not going to listen no matter who gives the advice
I used to be one of those people
had to learn everything the hard way

Can? You bet. Is it appropriate? Not often.

You can try. Whether or not it's well received....

I do

Yeah, if you don't start immediately blaming them

yes.
