Kinda wonder if they grill people and only actually suspect the ones that can name everything off letter perfect in minuscule detail, no matter how obscure or far back as possibly being alien robots ;0)
I tend to remember things by current events association too. I got my first passport in 1977, but frack all if I could say the month. I was eight and the only reason I recall that is because Star Wars was coming out and I was bugging that if we were gone I might not get to see it the first weekend.
The last time I had to get a new passport was April 2009, but I probably really only remember that because Miles' mum died the week after we went over to see her in hospice care that May.
I've gone back to college a total of five times at this point and can only recall the years because of the notable messes that precipitated having to stop: 1989 (chicken pox), 1991 (Dad's wreck, Mom's surgery, grandfather's cancer), 1999 (Hurricane Floyd and a back injury), 2010 (recession program cuts), 2014 (program investigated for funny money). If I had to pin down the month or date I'd have Fail Brain.
