Don’t lead people on and then drop them. That’s not fair. It’s mean and nobody should do it. Ever. Respect the people around you. Respect the fact that they’re human and they have feelings too. Don’t be selfish about emotion. Think first. Be thoughtful. Be kind. If you must break a heart, do it in the most positive way possible and never leave any loose ends. Don’t leave someone in the dark. Don’t pretend.
Do it right.
