I ended up leaving that money at home since I was not trying to repay it.
Are you absolutely positive that you left the money at home instead of at the hotel?
Yes, it was a home. I was with my girlfriend at that time as well as other people.
Repaying debts is important. If you fail to do so then the lender won't trust you in the future. If you repay your debts you'll have a good standing with the lender and they may be willing to lend you more money in case of an emergency.
It's okay to not be trustworthy because I don't need to borrow money again.
You should really try your best to make sure that you pay the debts you owe so you can build credit. Credit is like the cheat code to life here in the USA, so having good credit is very important!
