I do not get dew point. (Confession is good for the soul.)

Simple.
The dew point (dew point temperature or dewpoint) is the temperature at which dew forms and is a measure of atmospheric moisture. It is the temperature to which air must be cooled at constant pressure and water content to reach saturation.

John- this might help. Pretty much a function of the ambient relative humidity
Dew point ...Human perception[6] ...Relative humidity at 32 °C (90 °F)
Over 26 °C Over 80 °F Severely high. Even deadly for asthma related illnesses 73% and higher
24–26 °C 75–80 °F Extremely uncomfortable, fairly oppressive 62–72%
21–24 °C 70–74 °F Very humid, quite uncomfortable 52–61%
18–21 °C 65–69 °F Somewhat uncomfortable for most people at upper edge 44–51%
16–18 °C 60–64 °F OK for most, but all perceive the humidity at upper edge 37–43%
13–16 °C 55–59 °F Comfortable 31–36%
10–12 °C 50–54 °F Very comfortable 26–30%
Under 10 °C Under 50 °F A bit dry for some 25% and lower

OK wise guys.....
Density altitude?

The temperature ones chilled glass needs to reach for moisture to begins forming on its surface.

A high dew point is when it feels like you don't want to dew anything outside.

Relative humidity is a sort of left-handed way of looking at dewpoint. The dewpoint number is what meteorologists use in their calculations, but relative humidity is what they give to Joe Sixpack.
The simplest explanation of dewpoint is the temperature at which relative humidity reaches 100%. What changes it is the amount of water vapor in the air. The less water vapor, the lower the temp has to be to achieve saturation (100% RH) and therefore condensation.
Just the RH number tells you very little. You can have an RH number of 50% or any other percent with next to no water vapor or a bunch of it. That's why dewpoint is more useful to the experts.
Density altitude relates to atmospheric pressure. Air becomes less dense as altitude increases, as we all know. But because the pressure at the surface changes, what you read on your plane's altimeter may not report your real height above the ground. So density altitude is a correction for the present barometric pressure. Pilots set their altimeters to a reported barometric reading so they know their real altitude.

I do not get dew point. (Confession is good for the soul.) Today was a good day to illustrate the point. SIC At least it was in Central Iowa.
We may know the time Ben Carson lied, but does anyone know the time Hillary Clinton told the truth?

We have lots of DEW plants in the mountains. It stands for Deer Early Warning. They're plants like mules ear and the like that, when the humidity is low, crunch loudly when you get within 10' of them to warn deer of your approach.

I'm determined to never understand dew point. It's a useless piece of information I never needed as a robust 12 year old, how important can it be?

when new dry kiln operators start out, sometimes they get confused with the wet bulb temp. and dry bulb temp in sequencing the drying cycle.
a few ruined loads of FAS oak, and they pick up speed pretty quickly.

Every few years we have a high pressure dome that renders altimeters inaccurate. usually in the winter.
