dismatched

I have two pairs of the same black trainers. One pair is newer than the other and I wear them for work. To distinguish them apart in the morning sleep haze, I threaded white laces into the scruffy pair. This worked well.

Today I am sat at my desk at work wearing one new trainer and one scruffy trainer with a white lace. I only noticed on my walk accross the car park. I wonder if anyone will notice.
