It will be a nice break even if it is small. Whoever chores they normally do after school or work is taken care of for one day.
In my case not much will have to change. I will clear the table after dinner and rinse the dishes. That is what my husband normally does. I know it doesn't seem like a lot but it can mean the world to your Valentine that you know what they do and that you are willing to take over just one day.
Let your loved one use the time that you are doing the chores they normally handle to relax, let them play on the computer or do something else that they needed to get done. Let them read the children a book or do something that they find fun. My husband will have about 20 minutes to play his game and relax on the couch.
