Two new places

The other day when i was out for a walk, I found two streets I’d never been on before. If you live in a big city, that might not seem very strange, but I live in a small town of about 20 000 people. It’s also an island. The streets in question were short and insignificant, but still, I found two new places within a ten minute walk of my home. It almost seems unreal. What’s more, my mom, who’s lived here all her life, hasn’t been on them either. Where were they hiding all this time?
