Have you ever noticed how birthdays and other special days tend to group themselves together within families? For example, in my own family there are five birthdays at the end of the year: Anne-October 8; Daddy-October 15; Eric-October 30; Elizabeth-November 24; and Nate-December 19.
That doesn't even include Mom and Dad's anniversary in September, our anniversary in late October, Nate's anniversary in early October, aunt and uncle's birthdays of which there are at least 3 in October alone, cousin's birthdays: I can count 2 in October off the top of my head, and Eric and Elizabeth's anniversary in mid-December.
According to Mom this means October is closed. We are no longer allowed to add birthdays or other "special event days" in October.
I'm finding that this crosses family lines as well. I think the last week of February to the second week of March are almost as action packed as any three-week period in October for Nathan and I. Our niece Sophie just celebrated her first birthday February 25, Craig's birthday follows quickly on the 27th, then comes my mother's on March 1 and finally Nathan's on March 9. (Side note: be gentle with Nathan on his birthday this year, he's turning 30.)
And those three weeks are about to get more involved: my brother's wife is due to have their baby any day now. She's due March 16, but I don't think she's going to make it that far.
