You see, that is the logo of the London Tube System. The names of the stops are in the blue bar that spans across the red circle. Upon approaching each stop, a pleasing British voice announces to the passengers, "Mind the gap between the platform and the train." It sounds so much more polite than "Watch your step." And it's just one tiny memory of London out of thousands that I will never forget.
I purchased this onesie from a little souvenir shop located near the University. It says 'Mind the gap". I bought it assuming I would never have kids, but on the off chance I did, I wanted to preserve this little memory. The onesie stayed in its packaging until I was about eight months pregnant and began preparing the clothing for the baby, and I've been patiently waiting for her to be able to wear it. Today was six years and one month in the making, and it was totally worth the wait.
