Naw, you're wise. I bring up our (very firm, concrete, well-thought-out, result of years of planning and strong philosophies, informed by personal experience as a homeschooled, public- and private-schooled child and ex-teacher-aide and ABA-teaching adult) plans to homeschol Rowan, who's one.... and I get amused responses along the lines of "Yes dear, just wait until she's five and you'll change your mind".
Not bringing it up until a) you have to and b) it's close enough to the event that people don't think it's a passing whim? That's wise. Unless you like debate... which, actually, I do, which is probably why I bring it up.
I think I smell a home business in "sympathy" We're Homeschooling cards!
Let's see...
[Front of Card, curly font, surrounded by pastel flowers and ribbons] To a Disappointed Grandma...
[Inside]
You're a very special Grandma
And you couldn't wait to see
Your children's children go to school
And learn their ABCs
But dreams are fleeting, Grandma
And we're sorry you'll be sad
To know we'll be homeschooling
'Cause we want to drive you mad.
This card is meant for treasuring
The last from us to you
For once we've locked our kids away
They won't learn nothin' new
Their social skills will soon decline
And writing will be scorned
Because it is the Devil's tool
So Grandma, you've been warned
We're sorry that your grandkids
Will be socially inept
(And jobless, broke and single too)
But after you have wept
Take comfort in the thought that you
Won't have to pay for Uni
They don't accept homeschoolers
'Cause we're all a little loony!
