I think it is a form of SI but it isn't doing as much damage as other methods. I think it would be a good alternative to help someone stop SI'ing.

I generally write letters if there is no other alternative way of saying something to a person. There is a particular person who I can't talk to rationally, so if they ask a friend to ask me a question I can't go back and talk to them as my words generally get confused so I find it easier to explain...
