As long as you are a human being and living in this world, you come from a particular family notwithstanding whether your family is still alive or not. Although it may be true that you, your siblings and other relatives come from the same lineage, but some differences still exist when it comes to character
There are some of your relatives you may consider them to be difficult in character while some others you relate better with. It is important to know that your family will always be your family whether nice or difficult. You can make a choice of your friends and life partner but you cannot choose the family you are born into or who your relative is.
For those difficult relatives, simply devise a best possible way to accommodate them. You might want to focus on any good quality which you have observed in them.
