Don't ever give anyone any kind of advice!
I've learned if you want to share an important piece of information with someone that you would like them to accept, remember, or act on... do not spoon feed it, many people seem to prefer/value conclusions they arrived at themselves... introduce a little of it, to point in the right direction, and allow them to work out the rest, if they wish.
I only just learned this! Why didn't anyone ever share this with me?!
I guess I had to work it out for myself!
