Me Then N Now

Once Upon Time,
When ever I see a girl and guy (Lovers)

Riding on bike and girl hugging guy from back,
sitting in a park side by side,
walking together with hand in hand,
entering to closed cabin of net cafe,

I feel jealous of that guy for his luck and the way he enjoying with his lover.

But Now I Started To feel like

"Oho' Poor Parents they don't know their lovely daughter became someones else love, "

Am I Wrong?
