Some of these are just precious, some rather bitter, and I can relate to both of those categories, A couple of nice categories! (Yes, couple is two, if you mean more than two, choose another word).
I am 55 and still take things too literally.
When I was really little, maybe 5 or 6, got a cracker jack prize (they used to have real prizes), that was a sundial. Now, to this day, I like to think it was brilliant of me, but I thought it ran on light, any light, so I had it on a table under a lamp. Heck, it was supposed to tell time, I wasn't thinking shadows.
In about 6 grade, apparently my teacher had noticed my literal interpretation of things, once asked me to put my fingers on the paper cutter, right on the edge, where you put the paper to be cut. She laughed her ass off at me when I did.
About the same time, my dad was using a circular saw, laid it down, I asked about it, said it was scary, he said "you can't cut yourself with one of those", so there I was sticking my hand near the blade, thinking it was somehow able to cut wood, but not fingers. (I still have all my fingers, amazing though).
When I was about 13, a girl said "Vet club", I asked "veterinarians?" "NO", "veterans?" "NO, She finally spit out "Corvette Club.
About 20 years my then husband mentioned an actress, that she look like "the girl next door", I didn't catch myself and said "Carol?" (the woman who lived next door".
Things I have believed over the years, that caused nothing but confusion and/or trouble- "Call me if you need anything", "If you watch my kids, I will watch yours when you want to go out", "I love you", "Will you marry me?", "I really want to meet your kids", "Let's have a superbowl party, you can make your fried chicken", "Our company has a strong work ethic", "Safety is number one at xyz company", "We promote from within",
I am glad I believe what people say, it makes me say things I mean and not BS my way through life. It's not that great for the people around me though
