Why would a man be interested in an ordinary woman while there are very beautiful and fabulous women?

If you cut off the end of that rectangle, you make it smaller, 2 * 3 and a separate nub of size 1 * 2

The more direct answer is to look at a rectangle with sides of n + 1 and n - 1, let’s go with n = 2

Have you ever had a scary dream about a loved one or friend soon after their death?

And you are left with almost a square. One less than the square of side n.

Do you have any attributes quirks sensitivities abilities etc that you've come to learn most people don't experience? E.g. dream with subtext or experience de ja vu regularly or know you experience life very differently from those around you etc?

The basic answer is that you cross-multiply the values in each factor:

n^2 - n + n - 1

n^2 - 1
