Well, for starters, pretty much the same as right-handers. Our left hands may be our dominant hand, but that doesn’t mean we can’t use our right hand. Isn’t that the same as it is for you right-handers? Don’t you use your left hand when needed?
Everyday things that right-handers do, so do left-handers. With most things manufactured with right-handers in mind, it can get interesting for left-handers. I’ve been around long enough to use most items without thinking about whether it’s a right-handed tool or a left-handed tool. Most of the time we left-handers just make things works the way they are.
I have had a few things I’ve used that would work much better in a left-handed model. Scissors are one of those things. Those explicitly made with a shaped handle for right-handed people don’t work for left-handed people. The handle’s not cut to be comfortable for us.
My fridge is one of those side-by-side ones. I open the fridge part with my right hand and take out what I want with my left. It’s much safer for my left hand to be the one that grasps the item and not the door. Now, I open with my left on the freezer side but will shift to use my left to hold whatever I am taking out.
As a left-hander, I don’t have many items made explicitly for left-handers because they are pricey. All the manufacturer needs to do is mirror the thing so it will work for a left hand.
Let’s go back to opening the fridge. These days most appliances, including your fridge, may have the option to change the hardware on the door so that you can open it left-handed or leave it right-handed. This option also helps if the space you are putting your fridge into won’t allow the door to open one way, you can fix it so it will open in the best way.
My dryer, when I got it, had the tools and pieces to change the door. I never did. The important part isn’t opening the door. It’s how conveniently I can get the clothes in and out. Same with a fridge, cupboard, car door, etc.
Left-handers open most things, just like a right-hander. The only difference is that we use our left hands and not our right.
All this living with right-handers can make left-handers seems backward or klutzy, but we aren’t. It just that the right-handed world is dominant.
