Notice how you can be talking about your pipe and point to it, sitting on the table. You can mention buying it at the market and smoking from it for a year. Isn't it interesting that you can slide between abstract words and concrete visual perceptions (with pointing) in one sentence? It makes it seem that the sentence is right up close to the perception of reality.

'For All' and 'There Exist' are not elementary concepts
These infamous logical quantifiers are considered part of the foundations of mathematics. But they are not at all fundamental and (frankly) have no business there. They are based on collection review methods and on pattern matching, as follows.
In the context of a collection, you need a mechanism for reviewing the elements of the collection.
In case of "for all", you have a pattern and look for a pattern mismatch during the review. If you find one you stop early with failure.
In case of "there exists", you have a pattern and look for a pattern match during the review. If you find one you stop early with success.
In other words, the logical quantifiers are not as fundamental as: reviewing a collection, pattern matching, and stopping early with a result. Some patterns have "opposites" and pattern matching one is mismatching the other. Absent such symmetry, matching is different from mismatching. If people wanted to think about foundations, they would think about that.

Saw a strange coyote today
Thought I would mention it. It was oversized, slightly short-haired, and a bit brindle colored. Acted skittish too.

A palindrome for my wife
Figured this one out on a long plane flight one time:

The elements of dieting
I lost 40 lbs in 6 months. So now I am an authority. Here is what I suggest:
1. Find something to sublimate the urge to eat - smoke, chew gum, ...
2. Embrace feeling hungry. You will go to bed hungry and wake up hungry.
3. Make the meals count: find ways to make a really delicious meal for <300 calories.
Everything else is auxiliary. I ate only lunch and dinner with a little drink in the pm. I had a few treats, like yogurt with agave. Olive Oil. Walnuts. Prunes. Cod Liver Oil. It is expensive to lose weight and have good nutrition.
