The numbers 11 through 19 are all pretty good in their own way, actually

11 - prime number, doing it's own thing. Acts like it's 1 but twice

12 - all round solid number. Inclusive of everyone except 5, which generally sucks and is a number for idiots

13 - prime number, long vilified by society

14 - left field seveny number and helps with fortnights

15 - bringing 5 into the 3 team, 3 being so much better. Mad respect for that reach across the aisle

16 - square of a square, fine if you're ok with squares. The start having sex number (uk)

17 - totally left field number, no one ever uses it or understands what it's for. Don't even need to mention it's prime

18 - high levels of nine-ness, first indication that 9 has so much to offer when you add up the digits. Lets you smoke, drink, do porn

19 - stealth number, hard prime. Real tease to all the centrist boot lickers who can only stand multiples of 10
