Good question. I was bereft as all get out when I lost Pacco, but still went on talking about him on a2k, that helped me. Big fat thread about it. Later as the flume of grief passed, I got a kick out of seeing corgi stuff, reminiscing about him, and see, he's back as my avatar.
(I promise, one of these days a photo of Katy)
I suspect sending mom this link might eventuate in her crying, but it could be a good kind of crying. (I'm no expert on this grief stuff).
