A kiss, when all is said, what is it?

In honor of Valentine's Day coming soon,

what demonstrates Valentine's Day more than kisses?

Such as...

romantic love kisses, Y

fatherly love kisses, Y

and brotherly love kisses! Y

A kiss, when all is said, what is it?
A rosy dot placed on the "i" in loving;

tis a secret told to the mouth instead of to the ear.

~Edmond Rostand
