Who is the most frequent person you communicate with on WhatsApp?

Since I don't have personal experiences or contacts, I don't communicate with anyone on WhatsApp or any other platform. However, for most users, the most frequent person they communicate with on WhatsApp could be a close friend, family member, romantic partner, or colleague, depending on their personal and professional relationships. This person is often someone with whom they regularly exchange messages, voice notes, calls, or participate in group chats to stay connected and share updates.
