I'm the queen of klutz! Tripped and fell on

Oh, my gosh.  Have you guys ever tripped and fallen in public and tried to pretend that everything was fine?   

My teenage son and I were at the checkout lane at Meijer.  My back was killing me from walking on concrete so long while shopping, so my son said to go sit on a bench and he'd unload the carts.  (Yes, there were 2.)  I proceeded to walk over to the bench when suddenly a guy to my left turned around at the same time, and I tripped over his foot and went kersplat onto the floor!  Embarrassing cannot begin to describe what I was feeling (along with pain!).  More like mortified.  There was a collective gasp from all who saw me on the floor!  The weirdest thing is, I fell on my face, knees and wrists, but the next I know I'm on my back looking up at several faces hovering over me.  The poor guy whose foot I tripped over kept asking if I was okay, and I said yes.  He and my son lifted me up to a standing position, and I hobbled over to the bench with both of them holding an arm. 

I'm sore from head to toe and worried about my wrists more than anything.  Putting ice on them when I finish writing this post. 

Any other klutzes out there?  I could write a book about all of my klutz incidents.
