bank deposits

Years ago, an old Native American wanted to borrow $500.
The banker asked him, “What are you going to do with the money?”
“Take jewelry to city and sell it.”
“What do you have for collateral?”
“Don’t know ‘collateral.'”
“That’s something of value that worth more than the loan. Do you have a vehicle?”
“Yes. 1949 pickup.”
The banker shook his head. “What about livestock?”
“Yes. A horse.”
“How old?”
“Don’t know. No teeth.”
Eventually, the banker decided to make the loan anyway. A few weeks later, the man returned to the bank with a roll of bills. “Here to pay,” he said, as he peeled off a few bills to pay off his loan.
“What are you going to do with the rest of that money?” asked the banker.
“Put in tepee.”
“Why not deposit it in my bank?”
“Don’t know ‘deposit.'”
“That means you give us your money and we take care of it for you. When you need it, you can withdraw it.”
The old Indian leaned across the desk, “What you got for collateral?”
