Go on a spa session
If you feel your mother is working hard for you, then take her to a spa session. She can relax from her hours of working in the kitchens. You can also take her to a salon and give her a new makeover. A good massage, pedicure and manicure always helps unwind the pressure.
Watch a movie together
Take your mom to the theatre to catch a movie. Go watch something she would like and spend that time with her. If you are in short of money, then get her favourite old classics and watch it at home with her.
