As somebody from the UK who moved to Finland, there's a big difference in the degrees of "Freezing". Sure in the UK somebody might say they're freezing at -5, but in Finland I've been as cold as -25, even in the South. (People in Finland are better dressed for the weather, and houses are all pretty new, so they're generally well-insulated. But there's probably some truth in the idea that talking to strangers becomes less appealing when you're wrapped in scarves, and winter-gear.)
