Thanks stopdog. I have dogs who I think I am attached to, like I am pleased to see them when I come in from work, love cuddling up on the sofa with them etc. etc. But I can manage in life without them.

I am dependent on water / air for life.....

Is that the difference? That I may be pleased to see T, to spend my session with them and may even think of them between sessions (attachment), but know I could be sad, but not devastated if they left (not dependent)?......(I don't think!)
