Hi Ward! Yes, exactly: we must handle our own emotions AND we shouldn't do things to deliberately hurt others. Alex was trying to reassure me that just because one person is upset/sad/disappointed about another person's choices, it doesn't mean that the latter did anything wrong. (i.e., if I'm not interested in someone who's interested in me, they might feel upset — but that still doesn't make me a bad person for refusing to give them what they want)

Thank you for reading!
