better friends

Yes, brothers will be more friendly, they can behave as from different families some times, like we can't just believe that they reside at a same house. To one's profit or loss, the other one doesn't much react for his brother. These things will not happen with sisters. Because sisters can not behave like friends. But they will be like two bodies and one soul. One can't digest if any bad thing happens to the other one. She feels like she is suffering. Sisters are emotionally deeply attached than brothers do.

According to my experience brothers are more better friends than sisters.This is because due to same gender can understand the problems more effectively.Where as sisters feelings are different and they dont know problems of brother.but if sister is of understanding nature then she can be better friend too.It also depends on age according to me.
