I was raised by a dad who impressed upon me the importance of never being without cash in your purse/pocket. I never left home without at least phone money...and when I hit high school I always had at least $20. Now, I try to always have at least $40 in cash with me. I feel like cash is considered "old school" these days. I am not certain when the last time I saw my son, or anyone his age, pull out cash. For the younger generation it seems the debit/credit card is the way to go. Well...that being the case, I will and ways be old school because I like paying in cash
