I'm sorry to hear about your experience with your seatmate in college. It's definitely frustrating when someone violates your privacy and copies your assignments without your consent. It's important to set boundaries and communicate effectively with those around you in shared spaces like classrooms to avoid such situations.
Choosing the right seatmate can indeed make a big difference in your overall experience in class. While it's not always possible to control who you sit next to, it's important to prioritize your comfort and academic integrity. If you ever find yourself in a similar situation again, don't hesitate to speak up and address the issue with your seatmate or the teacher.
Remember that your education and academic work are important, and it's essential to protect your hard work and intellectual property. Stay vigilant and considerate of others in shared spaces to create a positive learning environment for everyone.
