Scenarios with a preliminary condition

Hi all,

I have a fairly technical question here, and since I wasn't able to word it in general terms I will just put an example (wait, I was eventually able to actually word it :D... go to the last paragraph if you want to skip the example):

Let's say I want to go with my son to a particular place in a trip, and that if we go he will need to skip a day of school. Since I only have shared custody of my son, I will need to ask his mother first if she is ok with him skipping a day of school. So, if I ask the I Ching about the outcome of my trip with my son, and the answer is about "discussions", "being on the same page", "be able to agree", is the answer referring to the trip (where if could be read as a bonding experience where there are interesting discussions), or that I will need an agreement with the mother first before considering this question.

On the other hand imagine that same question and the outcome of the reading is about friendship, bonding, journey, etc., but that it turns out his mother is not ok with me having this trip with him and it doesn't happen. Was that reading referring to what it could have been, ignoring the fact that there was a preliminary condition for it to happen?

So I guess my general question is: when we ask a question about a scenario that has a preliminary condition in order for it to happen, your experiences are that the I Ching is usually discussing the outcome of the scenario, the probability that it happens, the way of handling that preliminary condition?
In those cases does the question need to be worded differently, split in two different questions for example?

Thanks for your input!
