I have been living in the USA since 1981 which is longer than I had lived in Poland.
For last eight years I live close to Los Angeles. In last few years I have developed desire to learn Spanish. The complexity of Spanish language is about half in between English and Polish. Yes, English grammar is the simplest. Pronunciation and spelling is the hardest. Polish is just opposite. Grammar is unnecessarily complicated with many exceptions. Polish feels natural to native speakers but try to teach someone or explain anything.
Someday I would love to visit Spain for vacation.
