Mr. Holmes, no child of mine ever has or ever will grow up in an environment of fluffy clouds and rounded edges. Electronics, pyrotechnics, and odd hours are more my style. So long as your living arrangements allowed for separate rooms, my child's well-being shall be my business and I will make quite sure he does not bother you.
Think about it, Mr. Holmes. I have raised one child on the road following alcoholics, addicts, and artists city-to-city as a single mother. No habit of yours can possibly trouble me unless that habit can be described as including homicide.
[ooc: Play it as feels right for the characters -- Marnie is an unusual and extraordinary woman with unusual and extraordinary approaches to raising children.]
