Simcha > But so many aspects of our life are not directly and explicitly dictated by halacha
There is a difference between halochos towards Hashem and towards a person (havero or oneself). In the latter case, you still have a halakha, but it may depend on the personalities of people involved. What is an appropriate challenge for one person, might ruin another. So, if you are asking for an advice, you should preferably ask someone who knows people involved or provide such information.
