Dear Friend,
I am happy to hear that you and your sister are in peace with each other.
I don't know what your BIL is up to. Most likely it has nothing to do with you -- maybe he just wants to fix up the house a little in case he ever gets someone to buy it.
I think your equipment is great. It is wonderful that you have found the communication technology that works for you.
'Sending you prayers.
M.
