I had a guy friend when I was fourteen years old. We were the best of friends and it was a strictly platonic relationship. We went everywhere together. We hung out during the week and on weekends. It was never even an option that we would ever be more than friends.
We had been best friends for about four years when he finally decided he wanted to kiss me. I think we were both about seventeen by then. We were playing a game of Scrabble and he just leaned over and kissed me. I didn't know what to do but I knew it kind of felt right!
To make a long story short, that kiss led to us becoming more than just best friends. We have now been married for three years and we have one child. And all of that was from an innocent game of Scrabble!
