Me and my friend were walking back home after college, along the same route I always took every day. It was a 20 minute walk, some of which was a country lane. I left college with my friend at 4pm and we walked to my home. We never stopped or detoured. Somehow we arrived to mine at 7pm. Something like 2 hours and 40 minutes just disappeared like that.
We've never been able to explain what happened.
