"What We Want" May Not Be "What We Want"

When I was a kid, I can remember wanting time to speed up. I wanted to be older.  Now, I’m at a point in life where I’m not quite as excited about getting older (although I’m not yet ready for the alternative to growing older). I wonder if, sometimes, God shakes his head and chuckles when He hears our requests, knowing that there are times when “what we want”, is not really “what we want”.
