Whenever I walk about and speak English with my partner we just get stared at which is quite funny.
Staring isn't considered as rude there as it is in the UK. Also people aren't as used to hearing foreign languages than people in a British city and are often genuinely curious.
it's quite funny that guys saying this theory are always built like skeletons
Not always and definitely not in my case, but then again, you are usually wrong and this is no exception.
