This strange beetle-bug was dithering about on the edge of the planter. [I didn't take time to edit the photo. ] He darted here and there, changing direction, seemingly without purpose.
As I thought of the kindly comments reassuring me that I'm not [really not!] becoming senile, it came to me. Maybe I have ADD--a lack of ability to stay focused sounds nicer than dementia.
However, if I'm really "losing it" I think I'm in pleasant company.
