The opposing litigant, the lawyer, and witnesses aren’t your friend. And just because your friends and family love you and want to support you, doesn’t mean that they’re always helpful. The other side is there at court to present evidence against you and ask for something different than what you want. However polite or even friendly the other side is outside of court, remember that when your case is called, they’re going to be telling the judge why you shouldn’t get what you want. You’re in litigation.
