Thank you for the opportunity to help you with your question!
I have 2 friends with whom I have regular contact but have never met them. I had met them on Facebook but over the months, we have started chatting on WhatsApp as it is more convenient to chat there. We also share mails over gmail.com whenever we need to share information regarding various topics of our interest like Yoga, sustainable living and freelancing. But our preferred channel of communication is chat using WhatsApp.
Please let me know if you need any clarification. I'm always happy to answer your questions. Kindly best this answer if it has helped you.
