This weekend, Ahmet drew a map of Bosnia and Herzegovina for me.
I met Ahmet at The Abbey Centre, a wonderful community centre where a Bosnian school takes place on Saturdays.
Ahmet drew his map showing the main cities, including Bihać where he comes from.
Ahmet told me that, in Bosnia, he was a professional. But he arrived in London not speaking English, and has since dedicated his time to learning English while working as a post man - something he likened to the Japanese Kaizen philosophy.
I'm delighted that Ahmet has drawn his map for me, particularly as it's my last map and I've now collected a map for every European country.
