I was in tesco earlier and as I was going to get a basket there were two people looking at each other and talking, then I realised that they were both on thier phones and were nothing to do with each other, but I still felt like I'd walked in on an intimate moment or into someones living room, I felt really discombobulated for a minute.
It still feels strange to me to see people walking around and apparently talking to themselves, thats the sort of thing that would of got you cated away to the happy tablet academy when I was young.
