What my friend told me was a general criticism to my way to interact with people. I wasn't hurt by the remark or the opinión from her and her friends. I believed her bc she was my best friend and I new she didn't want anything bad for me. I was hurt for what the remark implied, you know, me like an inadequate person.
I asked her, of course.

There something that I still haven't understood. You put the stress on how we can hurt people with our behaviour, so it's normal that people are trigged to make us know that we did something bad.
Ok, this time the criticism is justified but where do you put the intentions.
I mean, I try to think people don't have bad intentions and don't act againts us on porpose. Isn't it something to take into account when you are going to point someone out a bad behaviour?

In the example I put about my frien, she couldn't give a single example. So, she wasn't very hurt by me. Today, is the day, when I still don't know what she meant. However, the remark is still with me. Why? I gave credit bc it wasn't only her friend's opinión but also her opinión.
