When winter becomes really cold we’ll get the pleasure to walk on the lakes we swim in in summer. Small Teufelssee in Grunewald was full with ice skaters and I was unhappy to have no skates. On the other hand: The bumps on the ice where rather big and I saw more than one skater falling down.
Another scary thing is the cracking noise and movement the ice makes under your feet sometimes. You never know what happens next 🙂
