Answer:
There is no such thing as a completely harmonious familly relationship 100% of the time. it you're telling yourself you have one with your family, then you're telling yourself a lie. life isn't lets all wear pink bunny slippers, hold hands, and sing Kumbayah. if you just want to have as nice a relationship w/ your family as possible, i suggest that everybody LISTEN to eachother. that is the most important part of ANY relationship.
