Half a House

What you'll be giving up when you marry someone that requires a dowry.

Sometimes marriage hangs in the balance because of the dowry. Remembering this term puts things in perspective.

I saved up for Half a House. But I think I'll invest it in the stock market and hit it big.

Half Blood Prints 

Notes, highlighting, or underlining from a past reader that is found in a library book or a used textbook and helps the current reader. Like the helpful notes Harry Potter finds in his Potions textbook in the sixth book/movie.

"Man, taking notes last night took forever!"

"Not for me. I got some half blood prints up in this copy of Grapes of Wrath. Everything I needed was already highlighted."
