I was in Phoenix today and stopped by my parents' for dinner on the way home. They had already made plans to have some friends over, so it was the five of us for dinner.

The friends turned out to be a couple of women. My gaydar hasn't been up to par for years, but I think it's safe to say they're sisters of Sappho. My dad even mentioned something to me before they arrived in his own ever-so-subtle way.

The comic gold came when my parents unwittingly said some things that to the outside observer who could appreciate the irony of their comments, i.e. me, was just standing there trying to contain my giggles.

The first comment came during a conversation of plants in yards and the recent high winds we've had throughout the state. My mom, bless her heart, asked the ladies if they needed any wood stakes. I think they both got the irony too, because they smiled when they told her no thanks.

After dinner, my parents and this couple got into a conversation about kitchen cabinets, which turned into - I kid you not - a tour of all the cabinet knobs in the house. At one point my dad remarked, "it's a knob exposition!"

I had to walk back into the living room so nobody would see the expression on my face.
