Pathological

I know this girl named Summer. She has recently been diagnosed with cancer. One pathological side effect was losing her hair from her treatment.

Placid

Every time I go to the beach, the placid sound of the waves crashing onto the sand and the bright sun soaking into my skin is very peaceful.

Antipathy

My antipathy toward exams is very large. I hate exams because their only purpose is to lower students' grades in their school courses. If a student has an A average in a class, they should not be required to take an exam.
