Right after I went to bed the other day, I received a message from my college sophomore "Can someone please loose the strings on the two instruments upstairs and the two electric guitars? they should just be loose enough to make a lower sound, not vibrate against the neck".    I was more than happy to do it, even not realizing what I was asked to do.  Thanks to modern technology, he was able to instruct me remotely. 
 

I took this opportunity and did an inventory of his room and his musical instruments: one piano, one amplifier, two guitars, two electric guitars, one keyboard, one portable keyboard, one violin, one harmonica, one flute, and some I don't know their names.   His room has been so clean and tidy, everything is in its proper place.

The house is so quiet now. I miss the noise those thing make.
