Being seingle - just like cute Susy Gala - can be an advantage when it comes to sight seeing. You can go whenever you like and do whatever you please. Peace, culture, party, sex... The best thing is not to make any plans and be adventurous in a city where you've never been before. The uncertainty of the unknown has its perks and can give you some nice surprises just like the one Susy bumped into as soon as she arrived in Barcelona.
