What does it mean?

What does it mean when people say, "Wow, you have your hands full!"?  Is that meant to be a helpful comment, or is does it have negative undertones?  Do my kids appear out of control or unkempt, or a combination of both?  Do I look wild-eyed and frazzled?  Or is it all of the above? 
(Yes, I realize it depends on the context of the situation, but I get this question/comment at least one time per week, if not more, and mostly from strangers.  And it happens everywhere - church, the store, the park, walking around the neighborhood, work, appointments, every.where.)

I oscillate between wanting to smack them and wanting to respond, "Yes, and I see that your hands are empty...would you like to step in and lend me one?".  But...I say nothing, but a simple and enthusiastic, "Yes I do!" and sometimes a laugh.  And I always share it with my husband.  We have an ongoing joke about this very topic.  It's like a mental tally of stating the obvious.  Because I know in reality, I do have my hands full.  To the brim.  Of boys.  Of wrestling matches, and never-ending laundry and dishes, adventures, cuddles, and sweet baby smells.  And my heart?  Overflowing!  With Goodness. Love. Laughter. Pride. Sweetness. Giggles.  Don't you see that too? 

Why is the next question out of that same person's mouth, "So are you gonna try for that girl?"? (again, mostly strangers) First of all...is that really any of your business?  And secondly, even if we do decide another child is right for our family, who are we to request that the baby be a girl?  And again, if we do have another baby, and it's another boy, does that mean we should be disappointed?  

Sometimes, I'm just amazed at what can come out of some people's mouths.  But mostly I wonder....what does it mean?  Maybe next time I'll just ask!
