In 2013 I visited British school in Bratislava where I met Helen. After 10 years I was in Delft and she had already moved to delft too. 
I called her and we had a coffee together in a nice cafe downtown and she kindly invited me to visit British school in The Hague. 
I was at school at 12:20 and after a short presentation, I had two workshops each 45 min. After my workshops we went out to plant a tree together where all students could touch the soil and dirt from the earth.
In my workshops I talked about shoe journey which is a subject I have designed for students to learn about materials they use and the effect they might have on our planet.
