Hello Johnny! from Don Juan Canto I, CXXIII [by Lord Byron]

Johnnyatthedoor

'Tis sweet to hear the watch-dog's honest bark
     Bay deep-mouth'd welcome as we draw near home;
'Tis sweet to know there is an eye will mark
     Our coming, and look brighter when we come;

                    – from Don Juan Canto I, CXIII by Lord Byron

(Ed note: Every reading of Don Juan yields a new pleasurable discovery. Johnny wasn't in our lives when I first read Byron's poem so this passage did not leave a lasting impression. — sdh)
