Bloody Good Samaritan

The other day I was waiting for the tram, when a lady holding a baby asks me in Dutch if the next one is going to the Brussels Midi train station. She, the baby, and her daughter were going to Antwerp. From where we were it's faster to go either to the North of Central station. Since I was going to Central I told them to follow me. So, the next tram arrived and we got on it. After which they more or less ignored me. Fine, you don't have to make small talk if you don't want to but in general people say at least a few words if someone's helping them. Anyway, to get to the centre you first take the tram till Montgomery and there you change for the metro. We arrived at Montgomery. I told them to get off and to follow me once more, which they reluctantly did. I lead them to the right metro stop. Then, I explained that next they will have to take the next metro, get off at Central Station, mount the stairs, go through the long hallway and go to track n° 5. This seemed to me quite precise. I sensed they didn't want to talk anymore so I backed off. The next metro came, I told to get on and I got on myself. They didn't move. From inside the metro I motioned to them to move before it was too late. The daughter waved at me with this strange look on her face which seemed to say "ok strange man go away now". After the doors closed and the metro was moving again I just stood there perplexed. I mean, I could not have been any clearer. They probably just stayed put for the next hour or so, waiting for the train to Antwerp. If they were lucky they found someone else who spoke Dutch to explain to them the same thing I already said. They totally ruined my good deed of the day. Fucking tourists.
