I'm from Eastern Europe and I've heard from native speakers that we use perfect tenses more often than a native speak would.

It is interesting to see how much easier it is to communicate with other non-natives in English than with natives. I always struggled with UK accent and considered the US version simpler. However it seems British have developed more tolerance for varying accents over time, while Americans have often trouble understanding anything I said. For them, there was only one version of any given word and I was not using it.
