I've been involved with plenty of women outside of the hobby whom I would politely describe as "capricious." It stands to reason that this would be even more true of those within the hobby community. It sucks either way. The more *fun* a woman is on a good day, the more likely it is that she's emotionally unbalanced on a bad one, in my experience. It just goes with the territory. If you find a dependable provider, then stick with her if that's what's important. But if you choose to grab the tiger by the tail--and we all have!--well, an unpredictable outcome shouldn't come as a shock, disappointing as it may be.
