I don't think it's necessarily a sign of adulthood creeping in. I think it's one obsession being replaced with another.
I'm a shoe/handbag kind of gal. Still am to a degree, but with less frequency. One day I didn't even recognize myself as I said aloud "Do I really need this pair of shoes?" I slapped myself and made the purchase. But I have noticed over the years that I have a "thing" for kitchen gadgets. the picture above is one of my purchases that has come in handy.
I love cherries-- but not the pits. Kalamata olives-- but not the pits. So... get a a de-pit-thingie! Plus, the hubs helps more in the kitchen because here's this cool gadget that shoots out a pit. For you parents, try shooting pits at the kids. If they misbehave-- BAM! Pit to the forehead.
Get out of the pits-- literally!
