Symbols of Love

Can one define love? Written for the 4W is Love? Contest.

Hot chocolate on a stormy night,
Soothing baths by candlelight,
My favourite meal, made just right;
Such sweet symbols of love.

Warm fire on a rainy day,
Cat on my lap, purring away,
Watching baby squirrels play;
Such sweet symbols of love.

A wish made on a shooting star,
My favourite tunes played in a car,
Letters, messages from afar;
Such sweet symbols of love.

A decorated Christmas tree,
A butterfly, so wild and free,
A single rose bought just for me…
How can one define love?
