I have my essay which is 3 pages long and want it to be around 5 pages , so basically all i want is to add 2 more pages. My essay is an argumentative essay about good samaritan. My professor told me that my essay is relied on sources alot and she doesnt want it that way. She says that i need to have a say and have my thoughts in my essay indirectly.
