Yet the majority of Mners consider this entirely ordinary and in fact desirable! Even assuming that an anonymous online forum may disproportionately attract unsociable introverts who prefer engaging with others via keyboards rather than face to face, what you describe can't be all that unusual, surely?
I've lived in enough places to have been made forcibly aware that ideas of 'normal' and 'weird' are both culturally specific. Finnish ideas about what constitutes 'introversion' are very different to those in the UK, for instance -- much larger idea of personal space, physical and emotional, far less smalltalk, more comfort with prolonged silences.
Most British people are far more indirect in their communication style than Dutch people, who aren't going to pretend your new haircut looks good if they don't think it does, and have different ideas about privacy (which anyone walking through Amsterdam at night will see -- you can look in uncurtained, brightly-lit windows into people's living rooms.)
I'm not a Brit, and consider myself deeply ordinary. When I lived in London and Oxford, I was 'ordinary'. When I moved less than 100 miles out of London to a large village near a city, I was suddenly deeply weird, despite being exactly the same person. Whether being a foreign, professional mother of one who cycles or walks everywhere is 'weird' or not depends on who's looking.
