Mother-in-law Day is a day to celebrate the woman who has been both a mother and a friend to you. Often, the relationship between a mother-in-law and her daughter-in-law can be a tricky one, but it's important to remember that your mother-in-law is someone who loves and cares for you, just as your own mother does.
On this day, take some time to show your appreciation for your mother-in-law. Send her a card or flowers, or take her out for lunch or dinner. Let her know how much you appreciate her and everything she has done for you.
