Third party candidates destroyed decades worth of progress we would have made on the environment. Without that bozo Ralph Nader we would have gotten Gore. Your vote matters. My philosophy is vote with your heart in the primaries but with your head in the election. No candidate is perfect. No party is perfect.
Curate a presentation on heartbreak. Talk about heartbreaks endured by people we know, fictional characters, historical figures, etc. Point is to normalize it, prepare them for it and teach them that they will come out the other side.
Anything you deny or fight will fight you back harder. Don’t fight the fear, pain, disappointment, etc. Let it in and let it teach you what it wants to teach you. Then you can part as friends.
Institute a “leave by” time instead of a curfew. That way they won’t panic / speed if something out of their control happens to make them late. “Leave Riley’s house by 10pm.”
