An inability to speak Spanish or Catalan makes it harder to socialise, network and meet new people, but there are a number of expat societies to help counter these lost feelings. Language is the key to integrating, although the Catalan versus Castellano play-off can sometimes make this harder. Finding a tandem language partner or group is a great way to combine language learning with socialising. But if you need a break from all the multiculturalism, there are a number of English-language social groups that you can join.
