I've realized that my habit of "going to the hardware store for bread" is something I do all throughout my life, not just related to XAH. When I realize that some people are good at certain things and others are good at different things, and that this should affect what I expect or ask of that individual, I feel a whole lot less put out and disappointed in the results.
It's also a big part of accepting that person for who he/she really is, rather than who I would like them to be. Life is a lot better when I can bear these things in mind.
