What is sacred?

The other day Dave was checking out an email or facebook post about sacred places.  He asked if I was interested in seeing them.  I say, Yes, of course I am.  So he clicks on the link.  There are temples, cathedrals, bodies of water, mostly buildings.  I began to contemplate: what is sacred as these were not what I thought of as "sacred"?  I guess my thoughts of sacred (being a catholic) were holy places in Israel; Lourdes in France; Ephesus; Our Lady of Guadalupe....

So here I go again broadening my horizon on what and how I think.  I recall when the kids were younger, they were constantly into things they shouldn't have been into.  I remember thinking "nothing is sacred" when some of my favorites were used as play toys.  What is sacred:  not my favorite lipstick or nail polish (why does my son have my nail polish?), not different colored thread, or yarn, not carpet or walls (why is there an art project in multiple crayon colors going on under the buffet on my freshly painted wall?), towels (what is my new plush hand towel doing in the garage), cups, plates, you name it.  And I am not talking just kids, yeah, the hubby got in on this action too.  If you treasured it, they got into it.

As an adult, it seems my view of sacred has become very narrow minded.  New things to contemplate, "what is sacred" to you?
