SAS 11.11

In China, 11.11 is Single’s Day.
I found this day very interesting, although 1111 looks like a solitude date on the calendar. It is not!

It has a prime factorization 1111=101*11,  and both 11 and 101 are primes. Therefore I think 1111 is a cute number and a Prime relationship day!

Some people may be like Composite Numbers, always have friends(factors). Others may like prime numbers, only solitude accompanies them. 
However, I believe all the primes number can meet up with other primes one day, and make a Composite Number! 
For those did not meet with other primes, I think maybe they are the precious Twin Prime.
