Great Points. My girl's job took her to NYC on July 5, so she asked me to come along, with her sisters and their husbands as well. We were supposed to leave at 12. From the first text message I sent her that morning, EVERYTHING changed, and we didn't leave until after 3. I was sooo pissed, because I had everything planned out in my head, and none of my plans played out, instead I 'went with the flow' as her ENFJ (by my guesstimate) brother advised me.
Yes we had a good time in the end, but it wrecked my nerves with all the changes.
