We have a date and a time. Tuesday, ten past ten.
I shall say bye to my cat, sit with him til the end and then probably take the morning off.
For all those who have commented already, I am overwhelmed. There is an entire world of sadness behind such an event and maybe not something that most people (luckily for them) ever have to deal with.
My heart goes out to all those who have gone before on this path. Thank you for your thoughts.
