Here's a little humor to brighten your presentations
Frazz and Opportunity Cost
I especially like the observation of the young lady in the last panel. One thing I like to stress with my students is that choices help us understand values.
Dilbert and Expectations
I like this one because it emphasizes that our decision-making process, for good or for ill, takes the past into account. Expectations are founded, in part, on past experience.
I welcome your observations.
