So I'm in this second hand store in Easton, Maryland. If you didn't know where it was it'd be hard to find. I bought a few little things, among them three little potted plants you'd call succulents. The next day I come to the same store and asked the lady how often I should feed and water the plants I had just bought. She got kind of a sad look on her face and said "Hon, those are plastic." I looked down at the floor for a second, then said "So once a month or so to water them should be plenty?" Then she's leaning on her arms on the counter and shaking laughing. Sometimes it's fun being stupid.
I am thinking of getting an ear bud just to wear. That way, talking to myself will be sensible to those around me.
I've caught myself talking to myself in the store. So I put my hand over my ear as though there's an earpiece there and have a "conversation" until I can slink off.
