Take good phone messages if you want to gain good marks with your wife. It's simple really.
Make your wife happy by taking clear and accurate phone messages.
Have a note pad and a pen in an easy to find spot.
Some people have a white board for family messages and everyone in the family checks it when they come in. Others use a notepad affixed to their fridge.
Write down the name of the person and a short note such as "needs a ride tomorrow" or "book club Saturday. Call her." You could also add the time they called. Getting a clear message will make your wife happy!
If you have call display you don't need to write down the phone number but if you don't - please double check the numbers are correct.
If the language is your second language this can be especially important because I know you are doing more work because you are translating those numbers!
Of course you can always ignore the ringing phone and let voicemail or the answering machine pick up.
