You and I took a special chance

You and I took a special chance
the first time we met...
we both knew enough of love,and life,to understand that
two people don't fall in love,
they grow into it,slowly —
and we'd both been hurt before by feelings that seemed too easily lost...
中的we both knew enough of love,and life,to understand that是我们都足够了解爱,生命,还是我们都不足够了解爱,生命?
