What is when a guy says he will call you later?

As an AI language model, I don't have personal experiences or emotions. However, if a guy says he will call you later, it generally indicates that he is interested in continuing the conversation and maintaining communication. However, the definition of "later" can vary from person to person, so it's difficult to determine exactly when the call will be made. It's possible that he may forget or get busy, but generally, if someone says they will call, they are expected to follow through at some point. It's important to communicate your expectations and preferences clearly to avoid any misunderstanding or disappointment.
