They may have information to share on successful conversations they have had with their college student. They may also have advice on conversations they wish they had or actions they might have taken. Be prepared to initiate the discussion. Communicate calmly and openly. You do not need to exaggerate.
Facts speak for themselves.
Listen actively and try to understand each other's point of view. Allow your child to express fears, concerns and disagreements without interruption or preaching. Role-play or use anecdotal scenarios. Work through potential situations your student may encounter in college using a role-play. Figure out a number of ways your student can handle each situation and talk about which works best and why.
