This is silly but I am very spoiled with technology. I normally pay by credit card and pay those by ACH transfer so I am used to once I pay, the money comes out and I don't have to think about it again. So when I pay by check and the person does not deposit it for a while and I have to keep remembering that $X amount of money is not really there, it annoys me.
I know it is silly and really not a big complaint but still, I can't stop it from annoying me. Technology has affected how our generation does things and how we expect things to be done. My grandmother balanced her checkbook monthly and paid most things by check or cash, now I use a check on average every three month. I check my balances online and pay by credit card or ACH. I have never used a full checkbook up, in my life. I wonder how much more technology will change personal finance over our lifetimes?
