Coming from Belgium, petke is also right about the influence of small language community. In example, in the flamish part (where belgian speak dutch), a lot of tv program and cinema is dub from english and even some cartoon. Where in the Walloons part (where belgian speak only french), we have access to the big tv network from France so we never watch anything in English.

But I remember reading that different languages use different sounds spectrum and hearing/understanding languages outside your spectrum is harder. Some languages have overlapping sounds spectrum which make learning different language easier. Now you have also the languages sharing the same roots and as you said somebody who know a germanic language then will have easier to guess/learn new vocabulary.
