We feel the same things, us humans. Pets have a way of getting right inside too and at times like this...Well, it's never easy. I feel sad about Merlin, but I know he had to go, as will Cleo and, indeed, me and you. It's just how it is. It's a reminder to live as best I can though, be the best person I can...And to not blame myself too much when I am not.
All the best, and thanks for the comment and heartfelt words.
