1. When taking off your husband's one and only house key to give to the dog sitter, remember to put it back on. This may come in handy at 9:30 at night when locked out of the house in a rainstorm with two tired boys.
2. Check your phone for messages and phone.....regularly.
3. Give neighbors a spare key in case you accidentally forget to put the one and only key back on your husband's key chain.
4. Did I mention something about hiding a spare key? Yea, do that too.
