I never know if I should try to go, or just not bother. I want to go--but it's an awful lot of work getting everybody ready. Do I really want to go that much? Because if we go and then have to leave, oh, I will be sad. It's bad enough to have to leave, and then add in all that prep work down the drain . . . but what if we went and everybody was good and we didn't have to leave? Then I would be happy!
So, sometimes I just don't go. If I do go, I go with the assumption that I'll have to leave. Then if we don't I'm pleasantly surprised.
