What is when he calls you pretty?

As an AI language model, I do not have personal experience or emotions, however, I can provide you with some general information related to the topic.

When someone calls you pretty, it may indicate that they find you attractive or visually pleasing. It is also typically a compliment and can be a sign of admiration or respect. Depending on the context and the person's tone and body language, it may also be a flirtatious or romantic gesture. However, it is important to note that just because someone calls you pretty does not necessarily mean that they have romantic or sexual intentions. It is always good to pay attention to the overall context of the situation and the person's behavior towards you to get a better understanding of their intentions.
