The Engagement Party of Abraham Grun

You've been invited to attend the engagement party of Abraham Grun and a woman you've been told is a formidable, very wealthy widow. She's dripping in diamonds in her hair on her neck dangling from her ears. Her stepson willies no slouch in that area either. Oh, he's got diamonds studs down the front of his shirt and a flashy diamond pinky ring. You think to yourself that the amount would likely be 640,000 or so, 135 years from then in the year 2023. I'm ordering math like that.
