When many people speak about their lives they tend to make comments like that they were "the first generation to finish college", "the son or daughter of immigrants", "the child of a single parent", "survivor of sexual abuse", etc.
But you never hear anyone say that they are "the child of parents and grandparents who went to college", "part of a family where all of their ancestors for 10 generations were born in the US", :"their ancestors came on the Mayflower", "the child of happily married parents", "the product of a great household".
It's similar to when people brag about speeding, running stop signs or not paying their bills but no one says that they drove the speed limit, drove carefully and have a high credit score.
Is it part of the victim mentality? Do people think it makes them look like they've accomplished more?
