I probably just wont get it. Which is sad, but it's my choice.
There. Fixed it for you.
I have had more than my share of addresses in the last 30 years. If I were to count 'em up, probably averaged a move once every two years (or more). Thankfully, that trend has curved well downward in the last ten years...as it will eventually in yours.
A number of circumstances has made it abundantly clear to me that having a driver's license with a current address is a legal requirement in most places, and a really good idea everywhere.
Yes, it's a PITB, and it shouldn't be that way. But life will throw you some curves. You can step up to the plate, or you can take your mitt and go home, bitching all the way.
