I feel your pain. My 2nd grade teacher was awful about it. Then of course, there are the scissors that never cut, spiral notebooks we can never completely fill, ink and pencil lead from the tip of your pinky to your wrist, and don’t get me started on gel pens....
I was on a bowling league as a kid. They had bowling instructors there but I was on my own. They didn’t know where to begin showing a lefty how to bowl haha.
My daughter is left-handed (as is her uncle and grandfather on her dad’s side). She never has been able to cut with scissors. We did get a pair of left-handed shearers, which helped some, but she is still cutting-impaired.
My youngest son, who grew up to be a nuclear engineer, was prevented from advancing from kindergarten to 1st grade by an ill advised teacher.
He was part of a class of 12 boys who were considered bad bets for being able to learn how to read. When I asked the teacher why, she said that he'd "failed a test". "What test?" One she had devised herself, it turned out.
The little boys were asked to "cut a circle" out of construction paper free had. I asked what kind of scissors he had -- whether they were left handed scissors. "No" was her answer. I pointed out that he was left handed.
Upon further investigation, I found that 11 of the 12 boys chosen for this all-boy class were lefties. I took him out of that school the next day and sent him to Catholic school where the nuns had him reading before Christmas.
Then there were the desks with the writing surface only on the right side....hated them.
As for sports, my post above about batting left-handed has some objective truth to it. Left-handed batters tend to do much better with pitches low in the strike zone and less well with pitches high in the strike zone compared with right-handed batters. The three home runs I hit in Babe Ruth ball were about two inches outside the strike zone below the knees. But that was my power stroke.
Unfortunately, I played enough baseball that when I tried to take up golf, I swung a golf club like a baseball swing. That meant at the top of the golf ball’s trajectory, it would make an sharp 90 degree slice to the left. I could never get it out of my swing. So I don’t golf.
I hate bowling..
You are so right about scissors; ironing is not easy, nor is writing in large books.
My mother gave up on teaching me to knit.
Not a pure lefty though - played tennis left handed, but hockey right handed.
