When you marry a person the family of your spouse becomes your family as well and this is due to the fact of your union. All of you are now each others' family. Like any other family your family may encounter certain rough roads along the way. It is normal that at times you may have disagreements with the other members of the family since all of you have minds of your own and those minds at times don't have the same opinions. The more people there are in a family then the more opinions there will be. At times these disagreements become a breeding ground for resentment and could damage your relationship all together. These disagreements usually happen between in-laws. It could be between the parents of the wife and the husband or the parents of the husband and the wife. At times it could also be between the husband and the siblings of his wife or the wife and the siblings of her husband. Simply stated, it commonly occurs between people who are related by marriage. It is quite challenging to adjust to having new members of the family that you do not quite know that well. You try to be patient and understanding but there are times that patience and understanding seem to have run out.
