I like that though - it shows how your relationship with Jonah progressed over the years. It was built on love and trust which grew between you.
And of course you'll take out the photographs - and the memories that go with them - and you'll remember. It's always painful initially, but again, given time, it does get easier because the memories make you smile, laugh, grimace, and it's all part of the wonderful friendship you fostered and nurtured.
I remember when Paddy was a youngster - he was such a loving and affectionate cat. Then when we acquired Flynn, Paddy withdrew - didnt like the competition, and he became much more reserved. He was always happier as an only cat. In his senior years, particularly when his health began to let him down, he became much more reliant on us, and his affectionate nature returned by the bucketload. When he was left deaf after his stroke at the age of 15, I would pick him up, put my throat against the back of his neck and sing silly songs to him. he would begin to purr hugely - he could feel the vibrations and they reassured him. It became our way of communicating verbally when normal methods failed us.
I still remember the day he came up, peered at me, promptly threw up into my handbag and then rubbed round my legs with his head. (probably trying to dislodge a particularly troublesome piece of vomit
). We loved our little man, and still do, even though he's long gone to us now. I love the fact that I find myself saying to Ross - Paddy would be so proud of you.......
You'll end up saying it one way or another to any new little snidge you take on - "Jonah would be so proud of you...." (or maybe: "Jonah would be shocked"
Either way, the interaction will make your heart glad again.
