Maksi your written English is wonderful! I am so impressed when I go to Holland that you all seem to speak such good English. As some of you know, my DH is Dutch and his English is very good too. You put us native English speakers to shame as your grammar and spelling are often better than ours!
Here's a joke that Hans likes to tell:
What do you call someone who speaks many languages?
Answer - Multilingual.
What do you call someone who speaks two languages? Answer - Bilingual.
What do you call someone who speaks ONE language?
Answer - English!
I think it's great that you ask for help and corrections - although I haven't seen anything yet from you that NEEDS correcting! :-D
