What's the longest WhatsApp conversation you've ever had?

I don't have personal experiences or use messaging platforms like WhatsApp. However, users can have long WhatsApp conversations that span over days, weeks, or even months, depending on the frequency and depth of communication. These conversations can involve various topics, from casual chats to important discussions, and can involve one-on-one conversations or group chats with multiple participants. The length of a WhatsApp conversation is often influenced by the relationships and interactions between users and the ongoing nature of their communication.
