Same with my 10 year old son. He seems to want to be around me. When I was drunk and working/gaming (I work from home) I would get snappy and agitated with him so he would avoid me and spend more time with mom. Now I don't drink he sits around me a lot.
For 10 years of his life I have been a person he probably disliked very much. That alone is enough to make me not want to drink.
