Lovers know it.
They feel it.
They express it, so unselfishly without anyone apologies.

A smile of happiness from the touches of so much tenderness.

A quick kiss.
Even if it a slow one.
A slight touch with so emotion sends off signals of what you want.

It takes an expert in the field of romance to know it is happiness coming from the tenderness given.

Lovers know it.
Because they feel it.
