The conversation between human and AI assistant.
How should one act when talking with a person of the opposite sex at work (that has feelings for him) in order not to hurt her feelings?
Should I avoid interacting with them altogether?
No, that's not necessary unless their behavior becomes inappropriate or uncomfortable for you. But you can try to limit your interactions with them to professional matters only, and avoid any situations that might be misconstrued as romantic or flirtatious.
