If your brothers or sisters are currently entangled in a fight, it might be time for you to step in. There are a number of ways to resolve the issue without causing more drama than necessary.
First, consider sitting down with each of your siblings separately to hone in on the issue. If they're both in the room, they're bound to argue and make things worse. Speaking to both of them alone will allow you to keep an objective stance in the process.
Once you have determined the source of the problem, you can all sit down together and hammer out a way to compromise. Sometimes, all that might be necessary is an apology.
If the problem continues, it might be best to speak with a gifted psychic. A psychic can use her talents to determine if there is a further underlying issue and if it's going to persist in the future.
