Oh alright Babi, you're right. That is unfair. I will narrow it down, somewhat.
Question: In a Friendship what is the most important quality, IMO?
As for 42, I had to google it.
For the literal-minded and those unfamiliar with terms like "base thirteen," this is a number system in which the number 10 is equivalent to our more familiar decimal 13. A base-13 number 42, therefore, is the same as four 13s plus 2, or decimal 54. So "six by nine" (six times nine) or decimal 54 is, in base 13, 42. For the mystically inclined, 42 in base 13 is the same as 110110 in binary (base 2). This could mean almost anything, and many Adams fans have spent untold hours discovering all of the places where the number "42" pops up. For example, there are many mentions of the number in the Book of Revelation. Others have made a game of finding 42s, such as these:
The angle at which light reflects off of water to create a rainbow is 42 degrees.
Two physical constants in the universe are the speed of light and thediameter of a proton. It takes light 10 to the minus 42nd power seconds to cross the diameter of a proton.
The sum of the ordinal alphabetic positions of the initials (SPG) for Stan (P.) Gibilisco, an oft-published science and technology writer, is equal to 42 (S=19, P=16, G=7).
A barrel holds 42 gallons.
Is it a guessing game, or a math game?
