When I'm running, I like nothing better than to get caught by someone I know. Then I can act all nonchalant and mutter someting like: 'Oh you know, I run all the time. I'm a runner you know.' And since I'm sweating like a pig and dressed in my running skirt and shoes I actually look like the real thing.
And the lovely thing about being a runner is that it impresses people. Sure, they may think you're crazy, but they can't help but admire someone who runs. Especially if the only running they do is to the fridge to get a snack.
As a mom you get much less admiration. After all, it's the second oldest profession in the world. As a mom the best feedback you can get is that you dón't look like one.
So I love to have my identity as a runner validated, and I take that validation home to the mom in me.
