Year 22 (XXII) was a common year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Agrippa and Galba (or, less frequently, year 775 Ab urbe condita). The denomination 22 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
22, plus 30, was the first time that i saw the truth
22, minus a week or so, was the first time that i knew
That i'd never be the same
That i'd only cry on name
Ever again
For any reason
Dearest, best friend
I am yours for now and every season
I'm holding your face in my hands,
'cause the following is sincere;
You are my future plans
So allow me one more half-year
If you're not here tomorrow
I wont be anywhere at all
If your hand is there to borrow
