What is he replied with a smiley face?

As an AI language model, I cannot give the specific context in which someone replied with a smiley face. However, using smiley faces or emojis in online communication can indicate a positive or friendly tone. It can also indicate humor, sarcasm, or playfulness depending on the context. Smileys can make the text more engaging and help convey emotions that may not be well-expressed through words alone. In general, smileys are commonly used in informal or casual conversations, particularly among friends or colleagues.
