Hello Carlton

It is a moving poem addressed to your mother. It is quite touching to read about the reasons why the cottage no longer has light. When the owner is absent, there is a deserted look about any dwelling despite its "good form".
The changes that life and age bring on can have deep shocking effect, like when the children are not able to visit parents because the parents suffer from health conditions.
It looks only the other day, that my siblings and I gathered around in the living room with my parents and having a nice get together. I wonder whatever has happened to those days of cheer and warmth.
To be sure, there is nothing like coming home to dad and mom and when we cannot do that anymore, we just become sad with remorse. No way we can change it.
Form and content-
Both complement each other. The short brief lines with a familiar remorseful theme syncs well with the readers.

It flows well.
