the noise DW heard was a window AC unit going on and off. Easy fix.

I get the 'auditory anxieties' once in awhile...sometimes stuff just sounds different.
That's on it's way here, tomorrows heat index will be 98.I don't plan on doing too much outside today. we are supposed to get into the high 90F;s.
Today will be pretty hot too.
Next week looks better.
