It was kind of the opposite for my partner and I. Apparently we first met when we randomly sat across each other in the University cafeteria. Apparently we even talked, but neither of us remembers it. We were in exactly the same courses too, just never noticed or remembered each other.
We officially met on Tinder like a month after that. Only our buddies who were sitting next to us in the cafeteria remembered that they (and by extension us) had met before.
We are inherently forgetful and unromantic though, this year we forgot our 6th anniversary and only noticed like 4 days later
Love that site, especially for just browsing categories!
