Routine is a good thing.  It helps one be consistent and if the routine is good then it is a vital part of progression because even if you're doing the same things over and over you can't help but get better at those things.  You know, that which we persist in doing becomes easier....  But life isn't always consistent.  So disruption in one's schedule is inevitable.  I hadn't thought about it much until tonight when I saw all kinds of things go differently then I expected them to go.  I didn't write 'go wrong' because different is different much of the time, although different can also be wrong or at least feel wrong.  When we expect things to be different as in Nicholas' new life, and Sheila starting to work after so many years one prepares the mind for that change and it can even be fun.  But it can also be a challenge and require us (me) to use the little gray cells to come up with something new.  Maybe that cliche about old dogs and new tricks has some application to this circumstance.  For a fact, I am an 'old dog' and I believe that I have dealt okay with 'new tricks' when required.  But I do recognize a certain trepidation about anything major that might come along.  And I have mentioned some premonition of just that in past entry's.  So if my minor glitches of today challenge me a little, what can I expect if something major pops up?  Maybe I just need to practice now so I will be better prepared later.  I do look forward to a time when I do have something 'major' to announce to the family, but certainly not any of these petty challenges like today.  But who knows what the future will bring?
