Well England, being the home of the Anglo-Saxons, means that it has a historical connection to the region that was made of the Germanic states, and is now modern day Germany. This shows in the language, because after the "end" of the Roman Empire in western europe, Latin usage was reduced in the Germanic region and their traditional dialects persevered.
Similarly, regions like Spain, France and Italy have lingual similarities because they retained the use of Latin more heavily, for some reason. Thats why their languages are called the "romance languages", while English and German are not.
Plus, in the medieval period French was the linga franca of Europe, so thats why we have words like rendezvous in English.
And seeing as all the people of these countries have just grown up using a variety of words of different historical and cultural background, i don't suppose they ever really find it out of the ordinary.
That said, i do find it a bit humorous when a person speaking welsh suddenly says something like "cafe" heh
