What has happened once will surely happen again.  Be it:

• Drama:  August - Lesson 59
• Unpleasant memories (read:  being sat on):  September - Lesson 29 
• Thinking before acting:  October-Lesson 34 , 
• Cooking events:  September-Lesson 36
•  Instinct:  October-Lesson 20
• Driving events:  there are too many to choose a single post.  Please, just go look at the driving label 
• Among a myriad of other things
