As a person
Born on the 20th, or any total of 20: an 11, made gentler by the 2 in front.
As a day
The 20th, or a date that totals 20, is an 11 day.
Good for weddings: an 11 day or a hidden 20 both count. Bad for flying.
Use exercise to burn off the emotion.
As a year
A 20/11 year is an 11 year: emotional and testing.
Friends and enemies
As an 11. Friends: 7, the best match, and 1. 3 gets on with an 11.
As an 11. Enemy: 9.

Compounds
2+0 = 2, and a 2 total always reads as 11, so 20 reads as an 11. Every 11 line applies to it.
The 2 leads, so it feels more sensitive than other 11s.
