“I, um —” Their stomach twists up. They hate when this comes up, it makes them feel inadequate, even though they know plenty of people who never went to college. They're hardly unique. There's no shame in it.
They feel ashamed anyway. They feel lazy, like they're just not trying hard enough. That's supposed to be the American dream, the immigrant who comes from nothing and works five jobs through college and then gets discovered as a janitor by a math professor or something. Morris' earlier comment about Michael taking care of them is sticking to their heart, too. That's not — that's not how it is. That's not what they want.
“No, I, um... never went to university. It's, um, too expensive.” What a convenient excuse! It's true, but it feels like a stupid excuse.
