"So, how long is your mom staying?" I ask Posh, who just turns away and laughs.
"OK, I guess she can stay," I say.
"How long?" asks the little girl.
"Till tomorrow," I say, and my wife just laughs some more.
Good thing I have a "thing" for the older ladies, which in my case means 70 and up. As I've noted in the past, women don't even begin to ripen till they hit 60, and most peak between 70 and 80. In that sense, Grandma is pretty ripe.
As with Santa Claus, I have no idea how old my mother-in-law actually is. Centuries, at least. But by all estimates, she will outlive me and eventually be driving my car.
"Hi, Grandma!" the kids say excitedly, welcoming her to California.
"I'm so glad you're here," one kid says.
"How was your flight, Grandma?" asks another.
Yeah, Grandma, which broom did you fly in on? Honestly, I love my mother-in-law. She is a good woman and a decent sport about the fact her daughter married well beneath herself.
To my wife's family, I have always been like some secondary lunatic in a Chevy Chase movie. For a while, my mother-in-law took solace in the fact that the relationship would obviously never last. Now, four kids later, my wife's family is beginning to acknowledge that it may be serious. Considering all that, Grandma is a very understanding person.
In her suitcase -- did I mention it was the size of a police cruiser? -- she's brought little gifts for the children and, for us, a photo album that pretty much chronicles our marriage -- first babies, first baptisms, first apartments.
It surprises me how skinny and underfed Posh and I looked back then. In one photograph, we look like a hot young couple. I think we were 14.
"See, in 1982 we were pretty hot," I tell the patient and lovely older daughter.
"Dad, those clothes are actually coming back," she says.
"White pants? Ascots?"
"Yeah, the hipsters are wearing that now."
Lord help the hipsters, casting about for edgy new looks and having to resort to styles we gave up nearly 30 years ago. In many ways, there is nothing less hip than a hipster.
Anyway, Grandma seems to be adapting well during her visit. Yesterday, she painted the bedroom a soft algae green and refurnished it with the sort of '50s furnishings Lucy and Desi used to favor.
Her suitcase is now unpacked -- did I mention it was the size of Cincinnati? -- and she is using my closet space for her 30 pairs of fuzzy slippers. It's a little scary to see her so comfortable around us.
Yet, I find Grandma to be a game and appreciative guest. We catch her up on the latest happenings around our house -- how a gopher snake slithered out of the ravine the other day, ostensibly to mate with the garden hose at the edge of the lawn. In our house, love and passion are almost everywhere.
"We called the fire department," the boy explains.
"Yes, we try to overreact at every opportunity," I say.
Like me, Grandma enjoys a little nip now and then (mostly now) and can eat an almost unlimited number of crab cakes.
She can tell a good story ("That man, could he talk! He had a tongue like a portabello mushroom . . . ") and her favorite sport is T-ball, for which we happen to have season tickets.
"I really like the price," I say.
"And the players are so friendly," she notes, as the 5-year-old second baseman curls up in her lap after the game.
"It is," I say, "like coaching a team of little elves."
"Or little gods," she says and hugs the second baseman.
It was a beautiful, sun-kissed evening at the ball field -- full with family. We couldn't get out of there slow enough.
