Love: We think about it, dream about it, lose sleep worrying about it, 
when we don't have it we search for it, and when we discover it 
we don't know what to do with it. We fear losing it. It is our source
of pleasure and pain but we can't predict which it will be from one
moment to the next. It is a short word, easy to spell, difficult to define,
and impossible to live without
