👉 Mortgage is like when someone lends you money to buy something that's not worth it, and they say "I have 70k to spare, so I'll loan it out for your benefit." It sounds like they're being nice and giving away their money without really needing anything in return.
Example sentence: "Hey, can we talk about this mortgage thing? So I'm thinking about buying a house, but I don't want to do it on my own. Can you lend me some money for the down payment?"
