In case of emergency:

Eric and I went to Chase this evening to join our checking accounts so we wouldn't have to try to use two different accounts to pay bills, etc., and so we would start seeing our money as OUR money, not "my money" and "Eric's money."

The personal banker we spoke with did her best to sell us on various products and services, and one of the questions she asked was, "Do you know what you would do in an emergency?"

Both of us: Umm...

Eric: Run around and start screaming?

Me: Look for a crowbar?

Obviously, she meant a financial emergency, which she then felt obligated to give examples of, which helped with clarity of the situation. But let it be known that should a REAL emergency arise, like an alien invasion or a zombie apocalypse, we will be well prepared.
