“A Love like this happens but once in a lifetime”
“A real, true love that makes a human being believe in the power of destiny happens only once in a lifetime.”
“If this had ever happened before, it couldn't be happening now. That's what they mean by 'once in a lifetime'.”
“It was a once in a lifetime thing. I hate to think it but I bet it's true. It's too bad for us that our once in a lifetime happened when were too young to handle it.”
“Opportunities like this come once in a lifetime!”
“I fell in love when I was twenty-six. Love in my interpretation comes once in a lifetime.”
