Please choose the correct ending to complete the given sentence: Relationships: [header] How to choose between best friends [title] Don't choose sides. [step] First, try to salvage both relationships by staying out of the situation as much as possible. It can be a tricky tightrope to walk, but it's often the best approach.

Ending1: [title] Be liberal with what you do and don't want in this person. [step] If either of you choose to have an affair, be sure that whoever you choose feels supported, cared for, and heard from by you. Ending2: If you can, try to keep friends at a distance. They will help you take the plunge if it's really necessary. Ending3: If you're dealing with a friend who's apparently already dating, pick your side. It's always best to state which side is the best, as you need time to reflect and to cut the friend out of your life. Ending4: [substeps] Simply listen if one friend talks bad about the other friend. Don't try to rush to their defense but don't agree, either.
