....my cousin's son just crossed the 9-month barrier with his girl, and he was like 'Wow, now its really serious'....and I was like 'Huh? What's so special about the 9-month anniversary?'....and then he was like 'It's important, because after this date, any babies of mine that pop up outside the relationship will be preeeety hard to explain'
..so that got me thinking, what other unconventional, yet important, anniversaries are there in most relationships? Feel free to contribute.
