*Not retired yet, but I feel like it sometimes*.
When you are all gung-ho about a big project that you're doing, and go to get everything together, only to find out you need a necessary piece....and all the stores are closed because it's a holiday/sunday.
*We paid off our house, and with no mortgage, our monthly expenses are $1k or less-- so I quit my soul-sucking job and am delivering pizza four nights/week. Three days completely off, and four days where I only work 5pm 'til 1-2amish or shorter. Yes, another (better) job is in the plans, but this summer, I'm working on remodeling the house so it'll be rentable.
