Idiomatic expressions and, to a lesser extent, the use of prepositions can be difficult at times. The English tense (better: aspect) system is also tricky. Since my mother tongue is rather primitive in that respect and hardly distinguishes between expressions such as I eat and I am eating and only has one grammatical way to talk about events in the past, it is sometimes difficult to figure out whether I need to use the present simple or the present continuous or the past simple or the present perfect.
