Hit the pause button, do her bidding and return when she has concluded her needs concerning you. It is called keeping the peace which often leads to getting a piece

. Really, it does not sound like she is asking a lot. Heck, I get the call for carring up the laundry basket (it is heavy) or getting the vacuum out, etc. No big deal, do it with a smile. Eventually, the list will run dry for the day and she will leave you alone. In all reality, help her make it through the day because one day, you just might need her to help you through the day and one only hopes she does it with a smile like you did.
