6 Times!!!

I don't really think it is my all time high but still pretty good for one outing to Target then Costco.  What am I talking about you may ask?  How many times I get "You have your hands full." from strangers.  Don't get me wrong, I am pretty sure these strangers mean something well when they say this, but I am never quite sure what "You have your hands full" really means or how I should respond.  "Thank you???" "Do I really look THAT frazzled today???" or "Yeah, do you want to lend me a hand instead of commenting on how full mine are???"  Any ideas or suggestions on what my response should be? In defense of all of the strangers, there was ONE stranger who responded to me "having my hands full" wonderfully!  An older Hispanic woman that didn't speak a lick of English came up to me in the parking lot, gestured to my children, raised her hands in the air and then sweetly put her hands on both sides of my face, all while saying something in Spanish that sounded very happy and celebratory to me.  (for all I know she could have been saying, "you and your children are stinky poo heads") but I smiled my biggest smile and said, "THANK YOU!"
