Consider ABCDEFGHIJKLMNOPQRSTUVWXYZ
Q is between A and Z
A and Z are not next to each other.
Nothing is between P and Q
P and Q are next to each other.
⎛ There is a gap between P and Q
No.
⎜ A gap isn't some _presence_
⎜ A gap is an _absence_ of whatever.
A gap in the real line is the absence of points.
Consider the real line.
For any two points x and y,
(x+y)/2 is between x and y.
x and y are not next to each other.
That is true for definable points only.
