I find this really interesting. 
Go to your parents. I’m assuming most readers here are around my age, born 1982 +/-.
So your parents should be somewhere around 60 to 80.
So go to your parents and give them a $100 note and ask them to break it. As in change to smaller denominations.
There’s a high percentage chance that they will be able to do it with the money in their wallets. Doesn’t matter whether you asked mum or dad. 
There’s an even higher percentage chance that they will be able to do it with the money within the house.

Somehow, the older generation still keeps this cash is best idea. Which is fine. They hold anything between $500 to $10,000 on their bodies or in the house. This, I find totally amazing. 

Usually, I don’t keep more than $100 in my wallet. I mean, why would I need to? Everything is on my credit card
