Knowing that when I get to work (I am a contractor) that there is going to be something "wrong" that was either not my fault, or totally out of my control anyways--it comes with the territory.
Knowing I work a crappy job and age discrimination, (yes it is real), makes it difficult to move on. 4-1/2 years and I can retire. I'll just "tough" it out at work, and come home and enjoy the music.
When I wake up after having ~5 hours of sleep. Generally each night I aim for between 6 and 8 hours of sleep. If I get less than 6 or more than 8 I will usually end up feeling tired the rest of the day. If I wake up after having had only 1-4 hours of sleep or so, it's easy to go back to sleep again. If I wake up after having 5 hours of sleep or so, I'm well rested enough that it's difficult to go back to sleep, but overall I will still be tired the rest of the day.
The screw-on lids for glass bottles and jars with smooth sides that shoot out of my fingers like watermelon seeds (mustard & taco sauce).
Bags that can't be opened without splitting them down the sides (chips).
Toothpaste in slippery tubes with snap open tops- why?
Bubble packages that are more secure than Ft. Knox, that you're apt to cut yourself opening.
Cardboard CD envelopes (I actually like jewel cases).
Anything that comes with Styrofoam peanuts.
Hearing/feeling the sound "TINK(!)" through my whole skull when my dentist has the drill at full depth on the last stroke of a root canal job. And knowing in a split second that the broken end of the titanium bit will not be coming out in any easy way.
Having 4 months of pain every time that I bite over there because the broken off piece of drill bit is still in there poking through the end of the tooth and hits bone every time.
Going back to that same dentist so that she can cut open my gums, fold back the flaps, and drill sideways through bone to get at the drill bit to remove it and clean up the infection.
Finding out that my dentist is very proud of the fact she never writes anyone sick and never prescribes anything stronger than Tylenol for pain (because you might not be able to work you know).
Not being to pour a nice stiff drink for the misery because I gotta take those antibiotics for the next week.
