The Garden Stalker

Does every garden have a garden stalker?  Someone who seems to know every time you drive a shovel in the ground?  Always hanging around hoping to get your cast-offs?  Or is it only me?  The doorbell rings at 8:50pm tonight, it's pitch dark outside.  Who would ring our doorbell at almost 9pm at night?  It's my garden stalker.  She stopped by to drop off some plant pots for my plant sale.  Which makes me wonder if she heard me say the other day I would give first priority to people who donated pots for my sale.  Was she hiding in the bushes, or was she just being nice?  Last weekend she stopped to ask if I was having a plant sale.  Then asked if she could have first choice of my plants, she said she would probably buy almost all of them.  You think I jest, but two years ago when I had my plant sale, she came over and bought every single hosta I had.  I had a lot of disappointed plant salers that year.  So last year I just made up a list of plants I had for sale and offered them to friends.  This weekend she offered to buy my house, said she didn't even need to see the inside.  I was just not allowed to remove any of my plants.  I did find out that if I start talking the science of plants, she quickly loses interest.  So is she just a wannabe garden fanatic like myself, just wants a nice looking yard, or is she a garden stalker?   Perhaps I am being a hosta snob?  Thoughts?
