Answer: Dear Mom,
When you next visit the grocery store, I have a few items to request of you. Firstly, please grab milk, because that is my main source of Vitamin D, a nutrient essential to the body's functioning properly. Secondly, I would like some frozen pizzas. These are perfect to throw into the oven as an easy lunch on the weekends. Will you also get some brownies? They are my favorite sweet treat!! Finally, I would appreciate it if you bought me some fruit, which provides the all-important Vitamin C. Thank you for your consideration!
