Based on the given context, craft a common-sense question, especially those that are LONG, INTERESTING, and COMPLEX. The goal is to write questions that are easy for humans and hard for AI machines! To create such questions, here are some suggestions: A. What may (or may not) be the plausible reason for an event? B. What may (or may not) happen before (or after, or during) an event? C. What may (or may not) be a plausible fact about someone (or something)? D. What may (or may not) happen if an event happens (or did not happen)? You can also create other types of questions. DO NOT make your question answerable without looking at the context, or question of which the correct answer can be directly extracted from the context. DO NOT ask a question that requires very specialized knowledge that is not common sense. DO NOT ask too simple or too short questions. Your question must be related to the context and answerable with common sense. Try to add more variations and complexity to the questions.

Context: Inspired by my recent Thai cooking class , I stopped by the local Asian food mart in search of galangal , shrimp paste and fish sauce for green curry sauce . As I stood in line to pay I spotted a big bin of freeze dried durian . Normally I only make last minute impulse purchases when chocolate is involved , but having recently seen and read so much about the much - maligned fruit , I quickly grabbed a bag and added it to my basket .
What is a good sign that I enjoyed my Thai cooking class ?
