Let me start by admitting I am an extreme optimist. The glass is not half-full, it looks more like 53% … maybe 54%. Wait, I think it is getting fuller! Excuse me while I go get a bigger glass, I am definitely going to need a bigger glass!!
My bride on the other hand is more normal. I would not call her pessimistic most of the time, but compared to me she looks like doom and gloom in a pretty package.
I have discovered, far more slowly than I should have, that rabid jump up and down optimism can be a bit annoying to some folks. By some, I mean the 98.2% of the world who did not get rose coloured contacts installed from the factory. Sure, my optimism can help balance out a bit of pessimism, but it can also be downright difficult for others at times. If I make the mistake of thinking I am right, for being optimistic, and that pessimism is wrong, then I become offensive. I have also learned “spiritualising” optimism by calling it faith does not impress people, and calling pessimism a lack of faith does not help anyone (or make you friends).
If you are an optimist, and especially if you are an extreme optimist, understand not everyone sees your outlook on life as a gift. Learn to use it to help and to balance, but do not beat people over the head with it. In particular, do not let your optimism become a thorn in your wife’s butt!
