Probably taking advantage of an escalator at Canary Wharf, or somewhere else on the JLE, the ad features people engrossed in their copies of The Week. I think the implication is that the man without the magazine is less aware of what's going on around him, even though he hasn't got his head buried in a magazine like the others.
I often think that when you're on the London Underground you tend to get lost in your own world and even though you're in a public place, you're often not aware of others around you.
Well, that's the only reason I can sometimes come up with for people not giving thier seats up to others who clearly need them. I have a real bug bear for people who don't even attempt to offer their seats to the elderly or pregnant. I've sometimes been so busy reading something that I've not noticed a person who needs a seat. In those cases I'd hurriedly offer my seat up when I notice, giving a hard Paddington stare to the other people who never bother.
If I don't have something to read I'll stare at ads, but in the absence of that I find it pretty impossible not to people-watch on the Tube. Having this blog has probably heightened my awareness of others around me, but I've always tended to people-watch. Are you the same? Are you aware of others around you on the Tube, or do you put up a mental force field, block out everything and let your mind drift away?
