To beginners having two languages doesn't really help that much.Absolutely. I am in awe of the people who are able to speak/type so well in English and am utterly embarrassed that my attempts to recently learn French and German have been dismal. Have learn't enough to speak it in shops and the like but not to have a proper conversation. I wish my school had spent a little time to get us speaking practical French rather than concentrating on repetitive grammar exercises. I would never make fun or comment on anyone's use of English. I try and make sure anything I type is correct only because I like to do that and turning off autocorrect really helps. I really do admire and am jealous of anyone who has two laguages.
Tried a few different apps for languages but I feel that I just suck at learning. Do make sure that before we go into a shop or restaurant that I know basic phrases though. My dad was of the embarrassing click your fingers and speak LOUDER AS THAT WILL MAKE SOMEONE MIRACULOUSLY understand English. That worked well when he wanted 3 oranges but ended up with 3kg of them. We were OK for vitamin C for quite a while!
For me being able to speak English with any real thought makes it really easy to communicate with people not from the Netherlands. But besides English you basically don't have to know any, since its basically the language everyone speaks (at least a little bit)
Although I went to France once in a people where tourism was basically non existent and me trying to speak English really did help because they couldn't understand me. Lucky I have my girlfriend who could speak a bit of France because I would have been lost there
