The only child
As far as you know there are 5 EVS in Škofja Loka now. Four of them are the only children in the family. Our EVS coordinator – Matjaz, was the only child also. So maybe, generally, people who were grown up without brothers and sisters are more interested in EVS? :-)
P.S. Poor Erhan, he is the only one among us who has sister, now he has to survive with us – egoistic and spoiled creatures :D
