I think coincidences are cool. I never think they mean anything, just cool.
One of the latest ones to happen to me was a couple of months ago. It was late night and Jaws: the Revenge was on...near the start the police chief comes into his office and the secretary says not much is happening, only Farmer Jones had some of his cows tipped the night before. The police chief asks what cow tipping is and the secretary tells him.
I figure I've seen enough and will come back later when the shark shows up and flip to another cable movie channel and Jeepers Creepers is on and I turn to it just in time to see two high school boys tipping a cow! This is about 30 seconds after it was mentioned on the Jaws movie!
I had something like that ..back in 1996 there was a song called "In the Meantime" that I liked and wanted to catch it on the radio (hey, it was 1996) I was reading a book and came across those words "In the meantime..." (I seem to recall it being a Mickey Spillane book for what it's worth) and so I thought I might as well check the radio and indeed it was on the radio, about 10 seconds in, which means it likely started when I'd read the words.
Another time after I'd seen Army of Darkness I was itching to use the line "Yeah...and I'll be a Chinese jet pilot!" (Ash says it at one point as a kind of "I'll be a monkey's uncle.") I used to volunteer at my church's Sunday night bingo and there was one old woman that used to complain in light-hearted away about how she never won. I was ready with "Yeah, and I'll be a Chinese jet pilot" as my retort when I asked her if she thought she was going to win tonight......but once I asked her she if she thought she'd win she answered with "Pfft...Yeah right! And I'll fly to China!" I nearly shit myself!
Yeah, I have quite a few other coincidences. Like my sister's birthday is Feb.21 and one of my brother's is Feb 21st too (they aren't twins) and both have since had children (my nephews) and both of them were born on Sept. 9th, but also different years.
Also my mom and girlfriend have the same birthday, July 9th, but also thankfully different years!
