A former to-be-mother-in-law once told me that the first thing she would look for with the boys her daugher brought home was: do they have polished shoes. Because she thought there were some details that were more relevant than other details. Sadly the whole mother-in-law thing went sour. Some sacrifices are just too big to be made, to gain a nice mother-in-law.
I have a similar thing. My last name is nowhere near the top ten of most common names, like Jones or Smith. When I find something in my letterbox wit an incorrect spelled last name, it goes unopened into the paper basket. My idea is that if people don’t take the small trouble to find out what my proper last name is, the purpose of their writing will not be meaningful enough to pay attention to.
Yes, and dislexia was written like that on purpose
