Should siblings support one another? Should they love or despise one another? Use each other as a source of competition? Answer below about your opinion. For sure there are sentiments of jealousy and anger for siblings. They try to outdo one another for acknowledgement. However, sometimes siblings just truly love one another but can’t express it. I have a sibling myself, for sure I do have arguments but I do love her. Overall, having a sibling is like having a best friend or enemy living with you for life.
