Talking to people bout how you feel is way different from complains.
If there is anything I hate so much in this world, then that's complaint. Some people complain so grumpily and annoyingly. It doesn't just go well with me at all. If there is anything that should bother you it's better to speak up than complain bitterly.
Complains can actually make someone loose an important opportunity I'm not just saying this but I have witnessed it.
I don't think complains should be fancied in any way.
