Lefty mom whose kids do things backwards

So I’m a lefty mom with all right-handed adult kids. As a mom I did what I could to teach my kids different skills especially sitting across from them to teach them to tie their shoes, crochet, etc. but my daughter was telling me that there are still some things that she does backwards like ironing that I never thought about. Her husband was telling her that she irons on the wrong side with the ironing board turned backwards. The next day, a coworker apologized for her backwards checkmarks, explaining that he mom was left-handed and that’s just how she learned to make them. What are some other things that right-handed people do backwards bc their parent was a lefty?
