I am old

It is a long-running joke between Darby and me that I am a grandma. (Actually, a lot of grandmas are cooler than me!) I go to bed early; I'm stuck in my ways; I don't take risks. More recently, my ambivalent attitude towards technology has added fuel to Darby's fire. I'm always complaining about "kids these days and their texting." And the other day, Darby and I heard a commercial on the radio for a vibrating mascara wand. This is how the conversation unfolded:

Me: That's stupid. Why would you need vibrating mascara?
Darby: I'm guessing it mimics the repetitive motion people use when they apply mascara.
Me: Yeah, but it's not that hard. Why do you need technology for it?
Darby: Well, if the technology's out there, don't you think they should make the improvement?
Me: No. If it ain't broke, don't fix it.
Darby: I can't believe you just said that, grandma.
Me: Well, it just makes me mad that scientists could be spending their time researching a cure for cancer and instead they're inventing vibrating mascara wands.
Darby: You are so old.
Me: If being old means you have some sense, then yes, I am old.
Darby: (dying laughing)

I've always thought of the "old" thing as kind of a joke. I mean, for the most part, I still feel young. But today, I realized that maybe it's not a joke. They were playing a game on the radio where the caller had to guess what a bunch of text message abbreviations mean. I was thinking, "Oh, I bet I'll know these. This will be easy. They'll say j/k, lol, stuff like that." Well, I was wrong. I only knew one of the six! Am I that out of touch? Do people even say lol anymore? Is that like saying "nifty"? I don't know what to think.
