Change

Well, sometimes it is, anyway.  Whether it is or not, change seems inevitable - nothing stays the same forever.
Some days, though, make me think that I've outlived my ability to gracefully accept the changes going on around me. 
Just today, the top headlines say that Toys-R-Us, which used to be like a license to print money, is closing 180 stores, and that College Park, Maryland, has decided to allow non-citizens (with or without Green Cards) to vote in local elections.
Stuff like that can make you question all of your assumptions, not to mention the sanity of your fellow human beings.
