Brat, you are lucky with speaking two languages fluently without having to work for that! And there´s no need to excuse yourself for not speaking German - German is really not a very important language.
I can only speak about myself - I really hate my only-school English and the fact that I´ve forgotten half of it during the past 10 years. And I´ve tried to learn Spanish several times, but I´m afraid my knowledge will always be on a very basic level.
So enjoy your Russian knowledge and if you want, we teach you some more important German phrases
