What's That Thing On Your Header?

I've been asked what that thing on my header is.  If you look closely, it's a footprint in the cement on our sidewalk.  I don't know who made this print or when, but we pass it every day.

In the spring, it is often filled with water after a rain.  In the summer, sometimes we find little blossoms that have dropped off the trees into the print.  In the fall, little crispy leaves fill it's shape. There is hardly a time we fail to notice this little impression.

We've been in our home 5 years now.  All three of my kids have measured their feet in this print.  Last summer, Birk finally put her foot in and like Cinderella, "It fits!"  She was so excited, but I felt a little sad.

All three kids have grown out of the print.  It kind of marks the passage of an era.  It seems like every day used to be full of firsts, but more often than not, I'm having a lot of days marked by lasts.  I know it's one of the  bittersweet qualities of life, but I sure am going to miss the pitter patter of little feet.
