I have some thing similar.... Except I always see 14:14.
But then again, maybe ive got a mental habit of lookin at the clock at the same time of day on most days...
...Just like the same way I seem to get up at about 3.30am to use the toilet... Maybe its just a habit?
And by mentioning the 11.11 thing, it'll stick in peoples minds who'd eventually subconciouslly look out for that time of day then, "Wow, 11.11!
How weird.. Just like that thread on ATS"
Just my thoughts.
