1. Easy sharing of daily trivialities: When the conversation begins to involve details of both parties' daily lives, such as work-related anecdotes, gossip between friends, personal preferences, or daily habits, it marks that the conversation has entered a more intimate level.
2. Emotional communication and resonance: Starting to share personal feelings, emotional fluctuations, profound insights about something, or aspirations for the future during a conversation, while the other party can provide understanding, support, or resonance, is a significant sign of intimate conversation.
3. Discussion of private topics: When the chat content touches on the private information of both parties, such as family background, past emotional experiences, personal dreams or fears, it indicates that both parties have established enough trust and are willing to show their more authentic selves in front of each other, which is the highest level of intimate chat.
