.....and what else, dazzlenation?...okay, that sounds like a plausible explanation.....lol.....hmmm....water....the refraction of light....flies with multiple eyes - put off by etc etc although another comment about how you look at it, in order to be captured by the CCTV camera above, sounds more likely....lol.....and what else?...why is this coming up, now?....all more than a bit 'deja vu' etc etc...anyway, i had once asked laura, in conversation about shared houses.....why a certain man had had so many fishtanks in his flat....wall-to-wall...he had found it difficult to move around....all piled on top of each other - against the walls as well as 'standalone', in the middle of his living room....apparently, his wife had left him because of his obsession and that is why he had been renting the flat....i had only found out - after he had moved, in a haste...to watch the removals men carry out etc etc...i had a quick look inside, whilst they were downstairs....almost unbelievable....anyway, can you guess what laura's explanation had been?...stranger than science fiction...something around 'surveillance'....lol....go figure:
