Becoming What We Speak

So we're in Walmart recently to grab a few things as our weekly usual. "Can we go look at the cakes?" our daughter asked as she and her brother began walking backwards to the bakery. I confirmed and made way to the produce nearby, when someone got my attention. It was a parent from the kids' school. Her oldest daughter was in the same class as our daughter a year ago.
"Haven't seen you in a long time," she commented.
"I know. Long time no see," I laughed, as I glanced over at my kids.
"Say. I didn't know you were part Mexican," she said.
"Come again," I replied- giving my version of Arnold's, "Whatchu talkin' 'bout Willis?" look.
She looked over at our daughter who now had her little brother in the headlock, forcing him to look at the cakes.
I snapped my fingers to get her attention, then gave her the rising eyebrows.
"Your daughter told me that you all were part Mexican and that's how you speak Spanish so well."
I shook my head.
"No. I learned to speak Spanish a few years back- not exactly fluent either," I responded.
I guess now that we have learned a few words in Mandarin Chinese, thanks to a little cartoon she watches, we will be part Chinese.
She has to know better.
