Are people's daily interactions different to the UK? I'm thinking about:
Body language, gestures, facial expressions
Personal space
Touching/ hugging friends and relatives
Social etiquette - holding doors, making room for others in the pavement, pleases and thank yous; is it like in France where you say "bonjour" when you go into a shop?
Queueing
Public shows of affection with partner (do people hold hands or kiss in public?)
Do young people "hang out" on the street or is that frowned upon?
Attitudes to public drunkenness?
Do people swear?
Etc
Thanks 
Some of these I can't answer as I have autism so am a bit oblivious myself. I'm told that Swedes are a lot more reserved in things like body language, but I don't notice it.
Social etiquette is a funny one. Immigrants find Swedes can be a bt rude, for example watching you struggle to get a pram on the bus and not offering to help. But they're not, it's just a different culture. Offering to help with the pram is rude because you're implying that the person can't do it themselves. If they can't do it, they'll ask for your help. But being independent and doing things yourself is very important to Swedish people. Hence the love of flatpack furniture.
Queueing, Swedes don't queue they wait their turn. Ticket machines are everywhere, even on market stalls. Take your number and wait your turn. DH says getting on the train in the evening is survival of the fittest.
Where I live you don't see people hanging out on the streets. Communities often have volunteers who round up errant teens and take them home. I've never seen anyone drunk here. I'm sure there are drunk people about but I've never seen it. Drinking in public is not acceptable, I think it may even be criminal. When there's an event like a fair in our town and the bar does outside service, they have to put up temporary fencing which completely screens the alcohol consumption from public view.
Swearing in Swedish is not really acceptable but my god, the swearing in English does my fucking nut in. Even on mainstream, daytime tv and radio it's 'fuck this and fuck that'. They really don't get how unaccpetable this is in English, they just hear it all the time in Holywood films and off the go.
