New chemo

I spoke with my father last week. He was having a cold (again) but he was OK, as much he could be.
Roxana brought them the baby, and dad was suddenly younger. His voice sounded young.
Magda told me that we are to fix his kidneys deficiency. He always had a kidneys problem but never really bother to fix. Today he started again chemo. One more month to go and then back to Debrecen he goes for follow up.
I noticed that he was in good spirit lately. I am not sure if is a permanent thing or just a phase.
I just realised that my parents do not know to function as a couple anymore. Is not the cancer that drives them crazy, but themselves, each other. They always had children around, grand children, etc. They only have been together as a couple without children, briefly before I come around..So that is why is so difficult now...
I succeeded to make them say I love you every time we finish a phone conversation. Isn't this something? They never say it in my family, they feel is wrong to do it...but now finally they say it to me. I am not sure if they will ever say it to my sisters, I think they will find that weird..
Anyway, I very much I love you too mom and dad.
