She would know that that smile is trying to communicate an intense positive thought process, such as "I am rising above the current stresses", with maybe a touch of "I am carrying on regardless", and a slight hint of "This will not beat me." While inside she is silently screaming, "I'm a mother, get me outta here!!" You notice this look in the supermarket, on the school run, at church, and coming in and out of caravans at Newday.
And as a mum, there is a look that you give back. It is a smaller smile, a more natural one. Not as intense as the manic/constipated look described earlier. It communicates to that other mum, "I understand" and it lets you know that you are going to be okay and that you will survive! Because in that moment, you want someone else to understand the stress or gritted teeth joy that you are experiencing.
I saw this understanding look as I was in the chemist at 10pm buying worm medicine. What a totally gross and embarrassing medicine to have to stand at a counter and ask for. The reassuring look came from the mum standing to the left of me not quite at this point, but when the pharmacist asked if there was anything else I needed apart from the worm medicine for my kids, and my hushed reply was "a bottle of head lice treatment please"...that's when the smile came. A comforting, "been there, done it" smile. She understood that the last thing I wanted to be doing that evening was buying these particular products, let alone having to admit that I needed them, revealing some of the secret horrors of motherhood. And then having to part with cash for the joy of owning such products. She also knew that that meant my following morning would be one of hair combing and linen washing! But she would also know that that is what you do as a parent, you care for your kids and help them, in all sorts of ways!
I was comforted by that lady's smile. And it caused me to smile too. I realised how I simply needed someone to understand my plight at 10pm that evening. No talk about it needed, just an understanding smile was enough. Its a tedious link, but I know My Heavenly Father understands my plight. He sees all and knows all. He knows what my groans are, the big heavy groans and the lighthearted almost comical ones. And He makes all grace abound to me because I am His daughter, so He knows what it is to love His kids, to love me. He knows I need looking after, and help and care when I get myself into a mess. And I know that the messes I get myself into are far worse than nits and worms!
"And God is able to make all grace abound to you, so that in all things at all times, having all that you need, you will abound in every good work." 2 Corinthians 9v8
