Howdy neighbor! Retired guy in Pueblo, Colorado (7 years tomorrow!).
First year was a major adjustment for me, always felt like I should be doing something, wondering what I was overlooking.
Things get worse after that. All your family, friends, associates in your various activities seem to think that since you are retired they need to help you out with lists of things that need to be done.
We must be creative in excuse making, otherwise we will never have any time off. I'd be happy to help you with that, but I have already made a commitment to an old friend who really needs my help right now.
Enjoy it! You earned it!
