When someone is talking on the phone to someone who isn't present, it can be challenging to tell if they are looking at you because their focus is directed towards the conversation on the phone. However, some subtle cues may help you gauge if they are paying attention to you or if their attention is more focused on the phone call:
Eye movements: Occasionally, the person may glance at you or their eyes might shift in your direction briefly during pauses in the conversation.
Body language: Observe their overall body language. If they are leaning towards you, maintaining an open posture, or nodding along with your speech, it might indicate that they are aware of your presence.
Tone of voice: Listen to their tone of voice. If they sound distracted or disengaged, it could be a sign that they are more focused on the phone call than on you.
Reactions to your remarks: If you say something significant or surprising, someone who is genuinely paying attention to you might react to it even while on the phone. They might smile, raise their eyebrows, or give other facial cues.
Awareness of surroundings: If the person reacts to any external stimuli or sudden sounds in the environment, it could suggest they are somewhat present and not entirely engrossed in the phone conversation.
Brief interactions: Sometimes, the person might take short breaks from the phone call to respond to you or acknowledge your presence.
It's essential to remember that people vary in their ability to multitask and show their attention differently. Some may maintain better focus on the conversation they are having on the phone, while others might be more adept at balancing attention between the call and their immediate surroundings.
If it's crucial to discuss something with the person, it's best to approach politely and ask if it's a good time to talk or if you can discuss the matter later when they are done with the call. Respecting their privacy and space during phone calls is generally appreciated.
