Do brothers and sisters need to avoid suspicion?

Whether brothers and sisters should avoid suspicion depends on the situation, their age/intimate or unfamiliar relationship/and family environment.

If the two sides have been close since childhood, and have grown up or even got married, there is no problem in sharing a room in this case, and there is no need to avoid suspicion.

If the two sides are brothers and sisters, but they don't live together for a long time, and the relationship is very strange, we should avoid suspicion.

If they are all children, young and ignorant, or one of them is insane, they may make a big mistake on impulse and hurt two children.

So in general, although they are brothers and sisters, there are differences between men and women after all. Once something happens, the whole family will be hurt, and it's too late to regret it. Not afraid of 10 thousand, just afraid of one thousand, it is very necessary to avoid suspicion
