A Little About Alot

Many of the blogs I read are about specific topics. My conclusion is these folks know alot about their chosen blog topic whether it's politics , gardening , sewing...I guess the reason I don't have a topic is because I'm not sure I know enough about any one thing to write about it consistantly. I do though, know a little about alot of things. This makes me pretty good at trivia but not really great at in depth conversations about alot. I guess I've never felt enough passion about one topic or issue to learn all I could about it and want to share my knowledge.
I know there have been times in my life when something caught my interest and I read everything I could about it and then when bored with it, moved on to something else. These days I have enough puzzlements at work that when I read for pleasure it's simply that, fiction that will take me away from my world and place me somewhere else for awhile.
My world, my life...now there's something I could write about and in fact have been encouraged to because it has taken very odd twists and turns and somehow I manage to always find my way back to normalcy ( or at least my version of it).
Random thought for today: Why do people rush to get in front of others to open a door at a bank, store, etc and then not hold the door for the person 2 steps behind them? Who besides someone on their way to a life threatening emergency could be in that much of a hurry?
