<p>My problem with IM is possibly disturbing my son when he is in the middle of class, typing a paper on his computer, etc. Is this a realistic concern or does your child only know you are trying to communicate when they are not busy? For example, Madbean said your child has to be on the computer at the same time. How do I know if I am not disturbing/interrupting reading something for an assignment, etc.? Thanks so much for the additional info. This high tech communication is new to me.</p>
