I had to look up a person’s email address at a Swedish university. I couldn’t remember the first name, only that the last name was Larsson. No problem, I thought…. I’ll just look for the person with that last name. Forgot for a moment that I was in Sweden where probably 1/5 of the country is named Larsson. There were about 20 choices.
I also happened to notice that out of the group of around 16 people I work with, 6 of us have names that end in “sson.”
