"...I Recieved a postcard from where he was. Perfectly chosen, cute and referencing a conversation we'd previously had. It said only one sentence, 'Dear S, I saw this and thought of you.' The warmest postcard I'd ever received because of all it meant. My own [ex] boyfriend had never sent me something so personal as that one stranger did, even before I met him. It brightened up my day, and convinced me that there were still so many happy coincidences in the world that I shouldn't give up just yet," goes A Warm Tinder Experience, the 75th entry in the #100IndianTinderTales series by Indu Harikumar, which she published on social media in 2016.

"Happy coincidence" is also a good way of describing how the illustrator, storyteller and recycler's experience of putting a question to strangers on the internet turned out — a series of illustrations about people's deeply personal accounts of their Tinder encounters, which got press, Internet and radio coverage all over the world.
