I think you might be, at least you have severe reading comprehension problems. Read my posts again, slowly. It may hurt your head, but try.
"no u"
top level comeback, truly worthy of an intellectual of your weight class
Literally your post: "it is hard to believe that they would've married at age 40 and started working with no previous experience"
The original: "My wife and I... worked every single day of our 30 year old marriage"
I know this might be a difficult leap of logic for you, but try to imagine: if somebody says that they worked every single day for 30 years... that is a statement about those 30 years and carries no information about what came before. It is an entirely valid interpretation of the same text that they started working in their 20s, have been in the workforce for 20 years, then met and married, and worked for another 30 years during their marriage. Magical, innit?
