My first overseas trip was from New York to Paris.I first had to catch a plane to Heathrow Airport in London and then change to another flight.When I got off the plane at Heathrow I saw someone handing out cards to some of the passengers,but I didn't know what they were for,so I didn't take one.Besides,I was too occupied trying to work out how to find where to catch the plane to Paris.When I tried to board the second plane they asked for my transit card,which I didn't have.I then realized that was what the card was for.I showed them my ticket but they said I need to show them a transit card too.I was worried they were going to send me back to New York.Instead they made me wait while they checked everyone's air ticket,and then they let me on board.The plane was 30 minutes late leaving London and some passengers got very angry.After that I was always careful to notice what other passengers were doing and to ask someone if I didn't understand something.
