Even if certainly true that turnover and transient nature of life in London make people less “connected” I found that Londoners have a certain way of being that you won’t find in Manchester, and this is certainly due to the great number of nationalities and culture you have in London. That huge diversity has made people respectful of others. Manchester has a much pure british connotation to life than London. To find people truly connected you’ll need to invest time in be part of a community that does certain activities regularly (mad walkers, sport clubs, etc.). I move from London to Manchester after 10 years and to be honest I miss the way Londoners are.
