I don't think it's rude at all I think the truth can be said in the nicest way possible and still upset someone sometimes so cutting straight to the point is easiest
If people aren't ready for the truth though they aren't really gonna hear what you're saying and defend the way things are which is sad but people can't be forced to change.
It annoys me when women on here complaint of abusive relationships and people tell them to stay and give it time. I know its hard, if my man ever hit me I'd be confused and wanna work it out but that's not the environment for me or my son. I'd leave.
Keep it real I say even if it hurts Dont lie or smooth over tell it like it is
It might be rude but you should do it anyway. Sugar coating things will or can cause complications later on. Yeah, you might not like the brutal truth but if you aren't straight forward things can progressively get worse. Don't ask for advice or share your story if you aren't prepared for any backlash, unwanted comments/advice, or the truth.
