please explain answer and label question

In this question, please provide examples of sunk cost, opportunity cost, and side effect from your personal experience or observation.

I also expect to have fun grading this question since it gives me an opportunity to know more about you. a) Provide two examples of sunk costs from your personal experience or observation. b) Provide two examples of opportunity costs from your personal experience or observation. c) Provide one example of positive side effect and one example of negative side effect from your personal experience or observation
