I would just put it in an envelope with a little note that says, "I thought you would enjoy this!" and put it on her pillow or somewhere else where she is sure to see it. Then wait to see what she says. If she says she can't do it because of work, you can say that you had hoped she could take the day off.
If my H had left something like that on my pillow, I would have thought he was expecting something in return.....like perhaps ML. If he had said that he hoped I take the day off.....I would have be furious! That is pursuing and pressure.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
