Abstract sine waves

From these three blooms, this rose was here when my late husband and I moved here almost twenty years ago. It seems to thrive on neglect :-)

Had an unusually bad nights sleep last night. According to fitbit I only got 3hrs38min. At least it hasn't caught up with me yet, so an early night me thinks. It was warm too. Has been warm here today too, had to put the ceiling fan on here in the study this afternoon. Temp gauge showing 23'C here inside and 28'C outside.
