Your woman is no servant, she does whatever she wants. But if she's in love, one of the things she'll want to do is help you out when you need it. This includes running those little errands that tend to pile up and become one giant chore. If you've been having a big week at work, don't be surprised if she notices and turns into your errand fairy to take some of the pressure off you.
Whether it's picking up your dry cleaning, buying some essential groceries, stocking up your wine rack (which is probably very necessary if you're having a massive week!), or cleaning up around the house, you can count on her to look after you when you really need it. The best part is that you won't even have to ask - she's got it covered.
