1. I would call my best friend who I've known for 14 years, and confess my feelings for her in the way that I had imagined in my mind. 2. I would call all those school and college friends and relatives I've lost touch with just to talk. 3. I would greet more people on the road and try to spark up a conversation with everyone 4. WhatsApp would become my least-used app since I am calling everyone for everything.
