Love is not love that alters when it alteration finds,
Nor bends with the remover to remove, Oh, No,
It is a true and ever-fixed mark that looks on tempests and is not shaken.
It is the star to every wandr'ing bark
whose depth's unknown, although his height be taken.
(Sonnet 116, Shakespeare, from my memory so it may not be perfect)
I like these lines, because although the demonstration of love varies wildly over time, the nature of love itself does not alter nor bend. And few people know this as deeply as mothers. We know that although we aren't often donning the lingerie anymore, that a well-made dinner or a thoughtfully-arranged date night mean a lot. We know that love often looks tired, but puts on a smile when bringing the child yet another bowl of cereal in a seemingly endless parade. We know, deep down, that our love is the star that guides our children and even our partners, back home, and that all other loves in their lives will be measured by that star.
So remember, today, what real love looks like. It looks like what you give to your family every day, or what you give to others, or even what you give to yourself. For love is a gift, true and steady, that brings everyone home.
