I agree absolutely with the price watchers. That's a pretty disgusting behavior as far as I'm concerned.
I trim my following list fairly routinely, but there are probably 100 on there that I hope will come back some day. It costs me nothing to keep them...
Fair call, no harm leaving them there; Who knows, they might come back.

Her husband had a job he could do mostly remotely with the USN and they told a great story. They used a small Hydro plant for electricity and used some of the water for home. I really wish she'd come back...
