Syd's last communication to me as I covered him up used to be 'I'm sorry' in a really plaintive voice. A couple of days ago that changed to 'kisses'. I sing him Baa Ba black sheep first which makes him go into a feather ball and position himself on his favourite sleep perch, but sometimes I hesitate before closing his door and he then goes into a whole conversation with himself.
My grandson used to do the same thing when little, practising words, I think Syd does the same going over his day until he settles down. It's soooo cute.
