Thank you very much for your encouragement and concern.
I have no problems using the business vocabulary in English but I realized that my daily vocabulary was so low... I was unable to name simple things like milk or ... carpet, or.. fuse... as none of those words are ever used in marketing or business books.
I never had English courses before so all I know I have learned alone. Me, books, and foreign (from my point of view) customers.
As I started listen radio and reading literature, those gaps are slowly levelling to an evenly distributed vocabulary, but i still have the grammar to improve.
I have settled well in UK, made some friends already, work is fine... too bad I am working in a Romanian team so my English is not so pushed to improvement.
I am already explore other challenges to fit my desire for a language and cultural better insertion into this society, and a new job is taken into account.
