I was at the supermarket and asked the clerk if they carried a certain frozen food brand.
We walked up and down the aisle. When we got to the end of it, she said, "I don't think we carry that line, per se."
Per se? I was loving her use of the word in this instance that we couldn't find the frozen, gluten-free Amy's macaroni and cheese.
"Hmmmmm," I responded, clinging onto the bravado of her using the word in this instance.
Try adding it to any sentence tomorrow. It's better than "like" and more interesting than "um."
