The phrase reminds me of my university days...when I wrote my first lines of C++ code.
cout << "Hello world" ; to be exact...haven't had much use of my programming skills lately.
No, the use of this phrase is in reference to the arrival of baby Lily (from now on called BabyL in this blog). Tomorrow BabyL is already two weeks old. Believe it or not, both BabyS and BabyL are born on the same day! So May 25th will never be the same @CasaR.
