<human>: Can you give me the gist of the text in a nutshell?

So once again, I was out shopping when a woman saw me with my four kids (8, 5, 3, 6 mos) and asked, "Are they all yours?"

I don't get it, why does everyone ask me that?  My kids aren't my little clones (only one looks like me the rest look more like my husband) but they aren't that different from me either.  They aren't adopted, and yes, they are all mine.  

Why do people who see me ask me that?  It always makes me wonder if I am doing something wrong.  The kids weren't misbehaving when she asked, but my three year old had just asked to get out of the shopping cart, so I was putting him on the ground when she came over.  

Course, I may just be annoyed because she didn't end it there... she continued to say, "There was an old woman who lived in a shoe.  She had so many children..." and then she trailed off...  Now, I know she was on the "children" thing **but** calling me an "old woman" was just adding insult to injury.
<bot>: Ranty, rant, rant, then "Yes, they are all mine" and btw, I'm not that old.  GRRRR....
