As someone who doesn't enjoy spontaneity, being outside my "routine" can be highly stressful. However, when I look back over the last year or two or ten, I see a pattern developing... just when I think we've achieved "normalcy," something changes. I think this might be happening to me on purpose. Maybe I'm not supposed to be comfortable in this life.
As my dad always says, "Blessed are the flexible, for they shall not be bent out of shape."
