I agree with the idea of having appropriate expectations. When you know someone a little, this is possible, but if you don't know them very well, it won't matter what you expect, and then there won't be any expectations, or it will be foolish to have them.
Exactly. Gotta get to know someone before creating expectations. If you get ahead of that, you're set for not only disappointment, but it's also sign that you have some things to work on your ego :-D
