Once, I had the chance to betray a friend that has always been truthful and honest to me. I didn't take the chance and stayed faithful to that friendship.
I recently had the chance to betray a friend of mine, but instead I stayed faithful.

It's so good you stayed loyal, I think anyone would've appreciated a friend like you.

We can all hope. I think most people would've acted the same way. 
user
Yeah because faithfulness is what defines a true friendship, after all.
