Who Balances Your Checkbook?

Recently, a friend and I discussed how our families balance our checkbook. Her husband handles the checkbook duties for her family. Her daughter never balances her checkbook. But simply looks online to see if there’s money in the account. I know of individuals who balance their checkbook by rounding down to the nearest dollar — so there’s always extra money in the account. Me? I balance my family’s checkbook to the penny each weekend. How about you?

Question: Which approach do you take toward balancing the checkbook?
