Where I'm going

First, on my holiday I'm flying to Singapore ( but only because I cannot get a direct flight from Australia to England).

Second, I'm flying to England ( if you were smart  would not have to tell you that).

Third, I'm  taking an underwater train to Paris ( in France).

Fourth, I'm taking a train to Venice (in Italy).

Fifth, I'm taking another train to Rome (still in Italy)

Sixth, I'm taking a ferry to Barcelona (still think I'm in Italy? Well you're wrong I'm in Spain).

Seventh, I'm flying back to England (why are you wondering why I said BACK to England)

Eighth, I'm flying back to Singapore (but only because I can't get a direct flight from England to Australia).

 Ninth, I'm flying back to Australia (if you were smart I would not have had to tell you that).
