Want to pose a question

My wife and I share a checking and a savings. Both our checks get direct deposited into the checking.

We use our joint credit cards (some in her name, some in mine) to pay all our bills, if they aren't on auto pay. Then pay the credit card each month.
I keep all my receipts and write on them, if it's not clear what they're for. She reconciles everything each month and we can see where ou money is really going.

I guess my only question is why did you need to keep track of your debits separately?
