Parent has a point. We accept this level of attachment in children, but do not encourage it, because, well, it is not really necessary, and could be detrimental, to daily survival. This level of attachment may be helpful to the original poster, but it is a valid question as to whether it is actually good for them in the long run.
I imagine the only con is extra spent brain-CPU cycles? Balance that against the benefit of a self-induced feeling of loving and the mental benefits that come with that like stability and stillness.
