What was a 14 y.o. doing riding around with $230 cash?
My kids carried cash because I wouldn't let them have one of my credit cards. Having $200 cash would have been unusual, but I expect it would be within the normal range.
Have you been to a mall recently. Jeans and a top for a teen can easily hit $100. Throw in a pair of sneakers and you can be pushing $200 in a heartbeat. I don't see that as a lot to carry.
Hey, people rob banks.
