Chocolate Chip Cookies

This is my Grandma's recipe!
Well, I changed a couple of things awhile back, but I can't remember what.

• ¼ c. white sugar
• ½ c. brown sugar
• 1/3 c. shortening
• 1 egg
• 1 t. vanilla
• 1 c. self-rising flour
• 1 c. chocolate chips

Cream shortening and sugars.  Add beaten egg and vanilla.  Then add flour to creamed mixture.  Finally add chocolate chips. 
Spoon-drop cookie dough onto greased cookie sheet.
Bake at 350º for 8-10 minutes.

When my aunt was little, and she had to bring a snack to school, the teachers and kids in the class would always tell her to ask my Grandma to make these cookies.
