I have a friend who can do the two finger whistle. She said her brother taught her when she was young. She says keep trying to do it and you’ll get it sooner or later and after you get it, keep practicing all the time. She said it took years. Whenever she does it, it’s earsplitting.
You know, the one thing I absolutely cannot figure out is dancing. I, absolutely and without question, cannot dance by the slightest and most generous measure. I have no idea where to begin or how to move so as not to emulate a catatonic tin man. I am a nuclear bomb of uncool on the dance floor. However, when I’m very drunk I do have a soft spot for simply laying on the floor and bouncing my whole body around. Now that is fun.
Also, what the hell is layered hair?
I was going to try to answer this, but now I’m confused, too.
I see similarities between some of those cuts, but nothing that all of them have in common.
Usually, it’s some variation on where all hairs are cut to the same length. The hairs on the top of your head will hang down shorter than the ones on the sides of your head.
Speaking of colors, I can never identify what the less common colors are: chartreuse, sienna, cerise, cobalt, cyan, taupe, sapphire, teal, ect. I can see the differences, but the names alone confuse me, and tax my recall.
Singing the alphabet or saying righty-tighty lefty-loosey isn’t a bad thing at all. Mnemonics are powerful memory tools.
For me, I have to sometimes think of learning to march as a cub scout to remember left from right. We always started off with the left foot, so it cemented my polar awareness.
Also, when remembering compass points, I have visual zigzag in my head as I mentally draw a line from North to East to West to South. It’s the way I remember the east-west orientation.
In a cafeteria-style food service line, the silverware (plasticware?) is nearly always at the start of the line. Some part of my brain believes it would make more sense to have it at the end of the line, when your plate is full. So I rarely remember to grab silverware - perhaps 95% of the time I have to go back to the start of the line for it.
Inability to learn from experience is frustrating.
Also, your left hand makes an L.
OMG, I thought I was the only one who knew that!
All I get are spittal-cover fingers.
Quantum physics stuff, and it’s not through lack of trying.
“Space-time”?
Time can bend?
Anti-matter? Dark matter!?
I know my left from right, but whenever I’m giving directions, I will point left and say right or point right and say left. Just follow my finger point and you’ll be fine.
I was in Marching Band in school. Five years worth. I cannot read music. I can play music according to the sheet music because I know what combination of finger movements make that dot on the page. I couldn’t tell you if it’s a A, C, F… When I’m singing, I just know that the next note is so many higher or lower than the last note. It was very embarrassing to have to sight read a piece of music.
Women.
Yep.
I’ve been reading music for over 30 years, in seven different clefs, and I’m still not very good at it. Sometimes I’ll stare at the page for 10 minutes trying to figure out what a note is. The worst is in bass clef, 4 or 5 leger lines below the staff.
I have to mentally put my right hand over my heart like I’m in grade school saying the pledge of allegiance to remember right from left. And while I have no trouble at all with north and south, if I need to go east (or west), I have to decide which road will take me in the direction of the Atlantic (or Pacific) ocean.
…And I can’t figure out how to memorize music, although I can sightread sheet music as easily as I read words. Funny how brains work. 
Me too! HIJK and TUVW give me a hard time. And I’m a librarian!
I still haven’t figured out how to eat a salad gracefully.
Subnetting.
Don’t try to teach me, I’ve learnt it several times.
Baseball whistles. Where you fold your lip down and just whistle to beat the band. The only kind of whistle I can do is the hand-whistle mentioned above.
Dammit. Me too.
Heh. My ‘which side is the left’ was finally accomplished by remembering which side my Brownie badge went on, when I was about ten. I still sort of vaguely reference that. But don’t ask me to give verbal left-right directions or we’ll never get there.
I understand how telephony works. And I understand more or less how planes fly. But on a routine basis, I tend to file them under, “If I think about it, I know how it works, but basically it’s the equivalent of magic.” Rather than actually trying to keep the information in my head.
