There is one point to be made, though. When advising, keep in mind that it might not be the whole truth (don’t express it, but realize it) and don’t suggest doing things that will make things worse if it turns out that this person has a mistaken, or biased, picture.
For example, if you tell someone how to give it in to someone for being mean, and it turns out that the one you are talking to is the mean one, you only worsened the situation. I did not notice this here. This is just some, well, good advice.
