Some of the critical stuff in life is pretty much invisible until you let it go too long.
Like tires (thanks to my sister for noticing that we need to replace one on the trailer….good to have done when we are parked and not on the roadside!)
And Chimney Sweeps. He is here at the house today doing one of our twice yearly cleanings (we burn the wood stove pretty much 24/7 from October to May so we need two cleanings a year to be safe). We learned this lesson the hard way two years ago when our chimney clogged and smoke began to back up into the house. (Imagine the volunteer fire department arriving to make sure we did not have a chimney fire!)
Now we have seen the light and have it done.
Other invisible things: roofs, plumbing, spouses. Don’t let the invisible things in life go too long without attention.
