Hearts for Valentine's Day

It's Valentine's Day and I spent most of the day doing school work or laundry.  Nothing too exciting!  However I am taking a few minutes to daydream on this snowy and bitter cold day.  I decided to google images that show hearts in nature and I was surprised to find some beautiful pictures.  When I retire I hope I have time to get into photography.  I love looking and beautiful pictures. Why am I so interested in hearts?  The heart is my favorite shape.
