Needless to say, this did not take much convincing on the part of Lautje and Anneke, especially since Lautje and the Opa are kindred spirits where trams are concerned: both get a thrill out of every single tram that passes by and impatiently wait the eternity of 45 seconds for the next one to show up, whereupon they are, once again, thrilled to see a tram and wait impatiently... etc. etc...
