Two people or two groups of people are fighting with each other and each wants to you take their side.

In a position between two or more sides in an argument or contentious issue, often leaving one without a clear course of action to satisfy either side.

It is a sad situation. There are two choices and you can not pick which is best. You can understand both sides but do not want to pick a favorite. Examples; I want my child to have sports lessons. I see the benefits for his health. He will make friends. I do not have extra money for the sports lessons. I am caught in the middle. I want to study abroad and I do not want to leave my boyfriend for ninth months to attend school in another country. I am caught in the middle.
