I've written a lot about how, as consumers, it's important to manage our expectations in order to avoid disappointment: You buy a game expecting it to have flaws, and you will yourself to have a good time with it. You'd be surprised how often that works.
What about the other side of the coin, though? Expectations aren't formed in a vacuum. Expectations, rather, are a combination of two things: preconceptions and communications. Each party has control over only one of those factors.
As customers, we have experiences which color how we view the world. Everything we've seen, everything we've heard, everything we've done affects who we are in this moment. Also this moment.
Yep. This one too.
Yes, I'm very clever. Yes, it's working out quite well for me.
