Just a month ago I lived in a house with sounds...The husband and two grown boys, their myriad of friends running up/down/in/out. Playing music, watching Rifftrax and Anime...Laughter coming from the basement all the time.
Now I live alone with my cat. No amount of music played can mimic the noise I lived in.
In most empty nesting times of life, the kids go off and the husband and wife stay in the house and adapt, together, to the lesser noise. Leave it to me to do it all discombobulated and be the one that left the nest alone.
I'm not sure I will EVER get used to the lack of noise....
