Just got stuck behind two youths in the queue Sports Direct - overtly tonguing each other and rubbing themselves up against each other for the duration of the wait. I felt distinctly uncomfortable witnessing such intimacy between two strangers at close range - like some kind of perve or reticent third member of a ménage a trois. I find it pretty revolting if I'm honest. I don't see the need for it and find it disrespectful, especially if you are trapped next to it in a queue or, say, on a train. Am I just a miserable and embittered (potentially jealous) person - or is it indeed, rude? Or perhaps I'm just afflicted with awkward Britishness. I noted they weren't British, so maybe we are just more uptight over here.
