Loving Lizards

Hello,

Put on your thinking cap.

Two lizards met each other on a wall.
They fell in love, at first sight.
One lizard said something to the other,
and the other lizard happily agreed.

Then, both lizards fell from the wall.

Why ?
What did the first lizard say to the other lizard ?

It said, "Let's have a hug."

Have a nice day.
